[-[[caption-width-right:300:"Halloween in UsefulNotes/NewYorkCity. ... A day when you fit in with everyone else... when even a teenage mutant ninja turtle can walk around in the open."]]-]

->''"Oh my, that [costume] is wicked! Who made that mask for you? ''It's exactly like the wanted posters!''"''
-->-- '''[[MasqueradeBall Masquerade Partygoer]]''', ''VideoGame/{{Dishonored}}''

For the paranormal, their mere appearance in a blissfully unaware society can cause chaos and panic. Thus, they constantly have to hide their nature from those not-in-the-know. Except for one glorious day... [[AllHallowsEve Halloween]]. On this singular day they could walk out and be among people who look like zombies, ghosts, goblins, sorcerers and demons. And all that they'll receive are glowing compliments on the workmanship of their "costume", and they don't even have to spend any money on it.. Or [[YourCostumeNeedsWork the opposite]].

This is the rare time when someone can be themselves among the populace and still do some good, or just have fun. They're also likely to enjoy a good MasqueradeBall.

While "Non-Humans and Halloween" is a popular use, the trope is really about how the circumstances of an event allow a normally secretive character to walk around in the open without destroying TheMasquerade, thus it can also happen at carnivals, costume parties or just claiming to be a weirdo who likes to dress up at random times. In effect they are masquerading as themselves, and even outside of having fun there are advantages to being the unnoticeable Clark Kent instead of Franchise/{{Superman}}. Similarly, this often results in an unusual sight of a SuperHero in their civilian identity but still wearing their actual costume.

Compare AllPartOfTheShow, YourCostumeNeedsWork, BruceWayneHeldHostage, IAmSpartacus, MistakenForAnImposter, HiddenInPlainSight and CityOfWeirdos.
A SubTrope of GenuineImposter.



[[folder:Anime & Manga]]
* Although haunted houses in school festivals are pretty standard, CuteGhostGirl Yuuko from ''Manga/DuskMaidenOfAmnesia'' decides to ''actually haunt it''. While she's usually a rather ordinary schoolgirl, she ends up making almost everyone who enters run out screaming when she puts her mind to it. She even manages to briefly traumatize one of the main characters.
* In the modern times, the titular ''Manga/{{Inuyasha}}'' went to Kagome's SchoolFestival wearing a hat to hide his [[UnusualEars dog-demon ears]]. When the hat was knocked off in front of Kagome's friend, she paid no attention, assuming he was simply cosplaying as some other random dog-demon as there were dozens of background characters dressed in cosplay-esque outfits.
** In a previous episode Inuyasha was in the modern world and was helping Kagome's grandfather with chores, wearing a rag over his head to keep dust out. He went off looking for Kagome and upon entering her room through the window he came across her friends. Because they couldn't see his ears, the only thing they were curious about were his white hair and yellow eyes and Kagome walked in on them having a pleasant conversation.
* If Takato from ''Anime/DigimonTamers'' isn't hiding him in a box, he's trying to pass Guilmon for a guy in a costume.
** In the first series ''Anime/DigimonAdventure'' too several members of Myostismon's group walk around in broad daylight. Wizardmon pretends to be a [[MagiciansAreWizards street magician]] (it's a wonder that worked out considering he's about 3 foot tall though); Pumpkinmon and Gotsumon were assumed to be kids in costumes.
* ''Manga/MagicKaito'': Kaito dresses up as his PhantomThief alter ego, Kaitou KID, for the [[MakesJustAsMuchSenseInContext skiing costume contest]].
* Shortly before his first battle with Mousse in ''Manga/RanmaOneHalf'', [[GenderBender Ranma]] was stuck in girl form by a [[TricksterMentor capricious]] [[OldMaster Cologne]]. So Ranma, desperate to keep the girl-curse secret, decided to humiliate [[ImprobableWeaponUser Mousse's]] [[HyperspaceArsenal fighting style]] by comparing his "Hidden Weapons" with cheap stage magic... and went on to fight "disguised as a girl" in a PlayboyBunny suit. The [[MaleGaze audience]] was [[{{Fanservice}} pleased]] (especially with Mousse near-missing Ranma to the point [[{{Stripperiffic}} she's left completely naked]], only to be promptly dressed up by Akane), but [[BerserkButton Mousse didn't take it well]]. The trick kind of backfired when Ranma remained locked as a girl afterwards, revealing his condition to the entire school.
** It's not like he remained; he briefly turned back into male thanks to Dr. Tofu hitting a pressure point on his back (and he knocks Mousse out in male form), but the hitch is that said pressure point only works once but never again. By the time Tofu reveals this, it has already started to rain on Ranma's head, so... You know what happens.
* Subverted in ''Anime/SuitePrettyCure'' where Ellen and and Ako actually wear costumes in Halloween.. Ellen, who is actually a cat stuck in a human body, wears a cat costume. And Ako, who is the princess of Major Land, wears a princess costume.
* In ''LightNovel/WagayaNoOinariSama'' it's first lampshaded by the older of the recurring fox brothers by him commenting how advanced make up is those days. It is then averted when a passerby sees him and runs away screaming ''MONSTER''.
* In ''Manga/SoulEaterNot'', both Shaula Gorgon and [[spoiler:Kim Diehl]] are witches who dress up in stereotypical witch costumes for Halloween.
* In ''Manga/MissKobayashisDragonMaid'', several of the cosplayers at Comiket are actually creatures from Tohru's world. Elma also goes to a mixer in her SpinOff (not fully understanding the concept) with her horn and tail visible, and claims that it's cosplay.
* ''Anime/DragonBallSuper'' has a non-Halloween variation, where Gohan is hired to be a stuntman in a Great Saiyaman movie -- and of course, he actually '''is''' the Great Saiyaman, but none of the crew knows this (other than his father-in-law Mr. Satan). At one point the crew gets suspicious since Gohan took the stunt costume home and later that day Saiyaman thwarted a bank robbery, but thankfully Bulma saves the day by saying someone broke into her workshop and stole the spare costume she'd made.

[[folder:Card Games]]
* The ''TabletopGame/NinjaBurger'' card game features a delivery scenario in an anime convention. It gives a large positive bonus to stealth, presumably because a ninja should have no trouble posing as a cosplayer.

* Creator/WoodyAllen did a routine where he bags a moose on a hunting trip, but it was only stunned, and wakes up tied to his fender riding in the city. Desperate to ditch the moose, he remembers a costume party he'd been invited to. He takes the moose there and tells the hosts "Hello...you know the Solomons." Things take a bad turn when the moose takes second place in a costume contest, [[YourCostumeNeedsWork to a couple dressed as a moose]].

[[folder:Comic Books]]
* One issue of ''[[Comicbook/TeenageMutantNinjaTurtlesMirage Tales of the Teenage Mutant Ninja Turtles]]'' is set during Halloween; when the cops show up after the big fight is over, they tell the turtles to go on their way, thinking they're just kids in costume.
** Also used by the turtles in an episode of the [[WesternAnimation/TeenageMutantNinjaTurtles1987 1980s cartoon]], where Splinter suggests they go as themselves to a Halloween party. They lose to someone who went as a Teenage Mutant Ninja AARDVARK (Who also happened to be the boss of the place).
** Similar in the non-canon (but Eastman-and-Laird illustrated) short story in the TMNT RolePlayingGame, where the Turtles go to a Hallowe'en party as themselves (and no one has any idea what they're supposed to be).
*** The irony is they DID have costumes, but the costumes got shredded in a fight early on in the story.
** One episode of the live-action [[Series/NinjaTurtlesTheNextMutation Next Mutation]] series had Mikey hosting an animal-themed rave, with guests supposed to show up in costume, allowing for this trope to happen. There was even a moment of YourCostumeNeedsWork.
** The 2003 cartoon revealed that for years Halloween was the ''only'' day Splinter would take the turtles to the surface and that they would trick-or-treat all day.
* In the first ''ComicBook/JusticeSocietyOfAmerica'' story, Hour-Man told a story of how he went to a costume party dressed as Hour-Man, and ran into a gang of thieves planning to rob the party, all of them dressed as Hour-Man.
** ''ComicBook/TheSpirit Holiday Special'' had a similar story, where-in a group of five criminals perform a late-night robbery disguised as the Spirit, and go unnoticed because it's Halloween. The Spirit manages to infiltrate and take down the group because none of them noticed a sixth man in the same costume.
* In an issue of ''ComicBook/HarleyQuinn'', Harley shows up to one of Bruce Wayne's masquerade balls in her own costume. She even introduces herself as Harley Quinn. He is actually suspicious - but then, he is Batman.
** He'd have every right to be even if he wasn't. As Tom Katers points out, thieves and supervillains in the DCU have a habit of breaking into high-class costume parties by pretending to be someone pretending to be them.
* ''ComicBook/{{Batgirl}}'''s origins invoke this trope, as Barbara Gordon created the Batgirl costume for a Halloween party, and didn't tell anyone about it, so that when she went to the party no one knew it was her, however when a group of criminals crash the party she defeats them as Batgirl and has used the costume since.
* An issue of ''[[Franchise/TheFlash Impulse]]'' has him going to a school Halloween party in his costume. He is, of course, not the only Impulse there.
* In Vertigo's ''ComicBook/PropositionPlayer'', Moloch and Anubis (of Hebrew and Egyptian theology) are looking for the protagonist in Las Vegas, the latter not bothering to hide his animal head.
--> Anubis: This is Las Vegas. We just saw thirteen Elvises play blackjack. They'll assume I'm part of some Egyptian attraction.
* Franchise/{{Superman}}:
** An old (and probably not canon [[RetCon anymore]]) ''Franchise/{{Superman}}'' comic has Supes going to the Daily Planet's Halloween costume party... as Superman! So he [[DeconstructedTrope buys a cheaper Superman costume]] (the spandex part is [=OK=] but the cape is a solid plastic piece which he has to throw away halfway thru the party), and goes with his glasses on, so that he's [[ClarkKenting obviously just Clark Kent disguised as Superman]]. It helps that every other guy at the party ''and one girl'' decided to go as Superman too, and many of their disguises [[YourCostumeNeedsWork were better]]. All this leads to one of the most amusing scenes in Superman ever, when the obligatory supervillains crash the party and he tears down his Superman costume to reveal his Superman costume.
** Something similar happened when Clark Kent was on a talk show. He and the other guests had been invited because they (and the host) had all been publicly suspected of being Superman's secret identity, so all of them wore the costume on stage.
** Averted in a Halloween issue of the ''DC Comics Presents''. Clark attends a costume party as Green Lantern.
** In a subversion, there's a ''Franchise/{{Superman}}'' issue where Clark and Lois go to a costume party [[http://27.media.tumblr.com/tumblr_kzljkmSppb1qbt9t9o1_500.jpg dressed as Batman and Robin.]] And then they stand around in their costumes sticking their tongues down each other's throats and...well, it's really hard to believe that the writers weren't poking fun at the [[Website/ThatGuyWithTheGlasses "Ambiguously Gay Duo!"]] [[MemeticMutation meme]] that sprung up around the [[HoYay rich single guy who dresses little boys in pixie boots and tiny shorts]] a long time ago. Also, Superman flatly states that Batman's going to kill him [[strike:if]] when he finds out.
** Also subverted in a Mxyzptlk story, when Clark went to a party as Green Lantern. When the crazy stuff starts and Jimmy Olsen, dressed as Thor, turns into a REAL thunder Tiamat and flies off, Clark surreptitiously uses his heat vision to heat up his fake power ring. "Look, Lois -- my ring is glowing!" "Maybe the magic is giving it real powers too! Can you fly after Jimmy?" "Well, I'll try..."
* ''ComicBook/{{Supergirl}}'':
** Supergirl sort of gets away with a variation of this a few years later in [[http://www.comics.org/issue/23416/cover/4/?style=default ''Adventure'' comics #392]]. It's Supergirl Day at Stanhope Women's College, so everybody's supposed to wear a Supergirl dress. Unfortunately, Kara flew through something radioactive and now her dress is being decontaminated. As Linda, she gets a replica dress at school, but has to wear it for some actual super-deed that leaves it badly ripped. She simply tells everyone she took it off because it was a bad fit and didn't look right.
** In ''Adventure Comics #404'', villain Starfire's gang is pulling bank robberies in the neighboring town of Carvale, where a Mardi Gras celebration is going on. So Kara goes to the party dressed as Supergirl in order to bled into the crow and capture the robbers.
* An arc of ''Legends of the Dark Knight'' entitled ''Idols'' features a craze among Gothamites for dressing as Franchise/{{Batman}}. Bruce Wayne attends a party wearing a bat pendant, then has to steal someone else's bat mask in order to save the day as Batman when there's a riot.
* In ''ComicBook/TheBooksOfMagic'', Zatanna takes Tim Hunter to a Halloween Ball. Halfway through, Tim looks at the wolfmen, vampires and [[BlackMagic black magicians]] around him and says, "It's just occurred to me, these people, they're not wearing masks, are they?"
* Played with in ''ComicBook/TheSimpingDetective''. Jack attends a "hate party" where all the local mob dress as various character from ''ComicBook/JudgeDredd'' canon as himself. Nobody recognizes who he is supposed to be until someone else turns up as Jack. Galen Demarco attends as herself, but in a manner that she appears to be her intelligent gorilla partner dressed as her.
* ''ComicBook/TheFlash'': Iris Allen was murdered at a costume party where all the guests were dressed as superheroes and supervillains. Not only did Barry Allen go as the Flash, but many of his RoguesGallery were there in their own costumes.
** Hal Jordan was there as well as Green Lantern, as noted by the Reverse Flash, might have been some other heroes as well.
* In several volumes of ''Comicbook/{{Empowered}}'', Emp dresses up as herself as part of a group of superhero team lookalikes for store promotions and such as her day job as being an actual associate member of the team doesn't pay. It is lampshaded how the costume she is wearing for the gig is much less revealing than her regular one.
* During the "Midnight" story arc, Batman says that he likes Halloween because he can walk around downtown in his costume and nobody cares. He even talks to a little kid, also in a Batman costume, who compliments his utility belt. Now for a bit of fridge logic, think about who Batman is in-universe (the story, as with many Batman mystery arcs, seems to be outside main DCU canon): a masked vigilante that terrorizes criminals, frequently framed for killing them...what kind of parents does this kid have?
** There's a story out there ("The Batman Nobody Knows!", ''Detective Comics'' #560) that suggests Batman's good at scaring criminals but not kids.
* A one-shot special of ''ComicBook/{{Shi}}'' telling Japanese ghost stories has the namesake heroine remarking Halloween is the only time she can wear her assassin outfit without impunity or being mistakenly attacked by her enemies. Lampshaded a bit when a trick-or-treater praises Shi for her costume, but misidentifies it as a costume worn by Zealot of the ComicBook/WildCATs.
* While ComicBook/{{Morbius}} is hiding on a ship, the ship's costume ball is the only time when he can go out and get some fresh air.
* ''ComicBook/SpiderMan'':
** An issue of ''The Amazing Spider-man'' has the Black Cat meeting Spider-Man at a costume party. She wears her own costume, but mistakes a random party-goer dressed as Spider-Man for the real thing. Turns out Spidey is InTheHood.
** During the JMS run on ''The Amazing Spider-Man'', Peter takes a tailor who designs costumes for supervillains to a safe place. The safe place? A Coffee House where he often goes in full attire, because no way [[HiddenInPlainSight would the real Spidey just hang out at a coffee shop.]]
-->'''Spider-Man:''' Hey buddy! I'm Spider-Man right?\\
'''Waiter:''' (''calling back'') Yeah... You're Spider-Man... nutjob...
** In one issue of "Spidey Super Stories", Peter goes to a Halloween party in his actual costume, except with a DominoMask instead of the real deal.
* Subverted in a Batman short story. During Mardi Gras, a guy dresses in a Batman costume, actually gets involved with criminals, and is rescued by the real Batman -- in a Zorro costume.
-->'''Batman:''' Even *I* have heroes.
* In one ''ComicBook/HackSlash'' story, an investigation takes Cassie and Vlad to a comic convention, where Vlad's monstrous appearance and creepy gas mask causes people to mistake him for a cosplayer. This wasn't intentional on his part, and he doesn't seem to get that everyone thinks he's wearing a costume.
* Another Batman example; in the ''WebComic/LilGotham'' Halloween issue, Batman and Robin are tracking down some criminals. Unfortunately, ''everyone'' is dressed up like a rogue or vigilante. Cut to the villains eating dinner and celebrating how they can go out in public without being arrested.
* In a one-page gag from ''ComicBook/TheSmurfs'', all the Smurfs attend a costume party dressed as Papa Smurf, except for one Smurf, who seems to be dressed as himself. The catch? The ordinary Smurf is ''actually'' Papa Smurf ''wearing a costume''.
* In ''Masks 2'' #1, Radio/TheShadow and Radio/TheGreenHornet infiltrate a masquerade party wearing their usual costumes. Green Hornet notes that he has seen at least three other party-goers dressed as him.
* In one ''Franchise/ArchieComics'', Archie and Jughead are dressed as vampires and accidentally get invited to a party full of real monsters, who are celebrating because this is the one day of the year they can walk around normally.
* Unintentional example: In ''{{Comicbook/Hawkeye}} vs. {{SelfDemonstrating/Deadpool}}'' Kate Bishop [[https://i.imgur.com/3jZHXCH.png meets]] the latter for the first time on Halloween and compliments him on "The best [[Franchise/ANightmareOnElmStreet Freddy Krueger]] make up I've ever seen" only to be flatly told by Clint that it's Deadpool's [[FacialHorror actual face]]. Kate merely smiles, shoots Deadpool a thumbs up and a happy Halloween, then turns around and [[ScreamingAtSquick silently screams at Clint]].
* One storyline in the 80s ''{{Comicbook/Eagle}}'' strip "Doomlord" has Doomlord going to a costume party as...Doomlord. There are actually five Doomlords there and the organisers decide to have an impromptu Best Doomlord contest. He comes second.
* At the start of ''ComicBook/{{WITCH}}'' Cedric and Vathek infiltrate a Halloween party. Cedric, being a ShapeShifter, goes out in his human form, modified to make it look he's wearing a costume, but Vathek is openly showing his ogre-like looks and wearing his normal outfit... [[CrowningMomentOfFunny And wins the prize for the best costume]].
** Later in the series, the girls go at a Halloween party in their Guardian forms.

[[folder:Comic Strips]]
* ''ComicStrip/CalvinAndHobbes'':
** The scariest example, no doubt:
--->'''Calvin:''' I'm yet another resource-consuming kid in an overpopulated planet, raised to an alarming extent by Madison Avenue and Hollywood, poised with my cynical and alienated peers to take over the world when you're old and weak!
** In another comic, Calvin asks Hobbes to come up with the scariest costume possible.
--->'''Hobbes:''' (''affecting a "ferocious" look'') Maybe I'll just go as myself!
%%* [[http://comics.com/jump_start/2008-10-31/ This]] ''ComicStrip/JumpStart'' strip.
* RJ and Verne in ''ComicStrip/OverTheHedge'' once went trick-or-treating without costumes. Being woodland critters, they were assumed to be humans in costume. Another year, they wore masks that looked like their CGI [[TheMovie movie]] counterparts. Ironically, Verne thought he was going as "some sort of iguana thingy" -- the very classification he hates getting from humans. [[RunningGag He hates being mistaken for an amphibian. At least iguanas are still reptiles.]]
* A ''ComicStrip/{{Peanuts}}'' Sunday strip has Snoopy watching as costumed trick-or-treaters get candy from one house. After they've left, Snoopy goes up to the same house and kicks the front door, then grins and holds his paw out. In the final panel, he walks off munching candy as the unseen homeowners comment:
-->"Who was it this time, dear?"\\
"I couldn't tell... some little kid in a dog costume."
* Played with in one ''ComicStrip/PearlsBeforeSwine'' Sunday comic. Pig and Rat go trick-or-treating on Halloween, but when the neighbor sees they didn't bother to wear costumes, refuses to give them any candy. After the door slam, the two remove their (fake) heads to reveal that each character was disguised as the other.
* An old Creator/CharlesAddams cartoon in ''Magazine/TheNewYorker'' depicts an AlienInvasion in progress, with one of the diminutive extraterrestrials being greeted by a homeowner and told, "I'm sorry, sonny. We've run out of candy."

[[folder:Fan Works]]
* In chapter 19 of Gamma Cavy's paired set of stories, [[https://www.fanfiction.net/s/10077874/19/Bond-Snapshots-Satoshi Bond Snapshots Satoshi]] and [[https://www.fanfiction.net/s/10002603/1/bond-snapshots Bond Snapshots]]which tie into a previous work of hers, Satoshi and Daisuke [[spoiler:who are not really human anymore due to sealed magic backlash]] go to a costume birthday party [[spoiler: fully bewinged]] and wearing clothes that belonged to their [[spoiler:now sealed]] other halves Dark and Krad. [[spoiler: No one figures it out, which is why they did it]]
* In the WesternAnimation/JackieChanAdventures fic ''Fanfic/QueenOfAllOni'', Jade goes in her new appearance for the Halloween chapter, going for maximum creepiness. Ratso, of course, [[WhatAnIdiot actually asks where she's going to get a costume at the last minute]]. Everyone just stares at him.
* In Chapter 30 of the ''Manga/MahouSenseiNegima'' short-story collection ''FanFic/ADayIndoors'', Kotaro rises to the challenge of playing the Big Bad Wolf in Little Red Riding Hood by transforming into his {{Wolfman}} form.
* In ''Fanfic/OfLoveAndBunnies'', Rocky attends Power Rangers Day in a cheap, store-bought Red Ranger costume. However, the mask was ''too'' cheap even for him, so he opted for bringing his actual helmet with him.
* [[Fanfic/PastSins Nyx]] has to play [[BigBad Nightmare Moon]] in a school play. Unfortunately, her costume is damaged, but luckily she also happens to ''be'' Nightmare Moon reincarnated by a spell gone wrong. Of course, she doesn't know this at the time...
** An [[RecursiveFanfiction unofficial]] sequel, ''[[Fanfic/RealityChecksNyxverse Nightmare Night and Nyx]]'', does this with a young filly [[spoiler:changeling]] named Flitter. Bonus points for actually being ''on'' the in-universe equivalent to Halloween.
** Another fanfic, ''[[http://www.equestriadaily.com/2011/05/story-unwelcome-changes.html Unwelcome Changes]]'', features Luna meeting a theatrical troupe who needs somepony for the same role..
* Played with in the Literature/HarryPotter[=/=]Franchise/JusticeLeagueOfAmerica crossover ''Terminal Justice'', where the League came to believe that Harry, who was disguised as "Mr. Black," was actually the Archangel Gabriel. When Harry later attended a League Halloween party while dressed as Gabriel, one of the members asked whether it was fair for him to attend as "himself."
* In [[http://crys.fanficauthors.net/Dream_Journal_of_Harry_J_Potter/index/ Dream Journal of Harry J Potter]], one of the chapters (all of which are supposed to be dreams Harry has) is a Halloween day where Harry (and Lily) get dressed as Santa's elves, Sirius goes as Santa Claus, James Potter goes as his stag form, and Remus goes... as a werewolf.
* Invoked in the [[HalloweenEpisode Halloween Fic]] of the ''FanFic/FacingTheFutureSeries'' by Tucker when he didn't like [[WesternAnimation/DannyPhantom Danny]] and Sam's [[ScrewYourself choice of costumes]]. The reason it was avoided was because the author had seen YourCostumeNeedsWork too much.
* In the ''Manga/{{Bleach}}'' FanFic ''FanFic/PleaseStopEatingTheHellButterflies'', the HalloweenEpisode list stipulates that Komamaru is ''not'' allowed to go to Halloween as himself. Mayuri, however, is.
* Can be found in a number of ''WesternAnimation/MiraculousLadybug'' Halloween fics.
** One premise, originating in [[http://hchano.tumblr.com/post/151111107016/stupid-ladybug-episode-idea a tumblr post]], involves Adrien being forced into a Chat Noir costume by Chloe, and Ladybug mistaking him for a transformed Chat Noir and dragging him into a fight without giving him the chance to transform. Fics using this premise include ''[[http://archiveofourown.org/works/8436457 Chat Noir's Spooktacular Halloween]]'', and ''[[http://archiveofourown.org/works/8439280 The Bat's Out of the Bag]]'' (though it ''wasn't'' initially inspired by the above post). The two stories take notably different turns after Ladybug finds out he wasn't transformed: in the former, she cracks up laughing, especially when he tells her he was forced into it, only to panic later upon seeing Adrien in his now damaged costume; in the latter, she harshly calls out Adrien in private for his supposed recklessness, only to get a similarly harsh rebuttal from him about how she has no idea what his life is like, which reduces her to tears and forces him to follow her home to apologise.
** ''[[http://archiveofourown.org/works/8292442 A Treat Sweeter Than Candy]]'' has Ladybug and Chat Noir spending Halloween together transformed while posing as cosplayers to anyone who asks. This somehow results in Alya and Nino ''immediately'' recognising them as Marinette and Adrien despite having fallen for their ClarkKenting dozens of times before.
* In the HalloweenEpisode of ''Fanfic/TheNewAdventuresOfInvaderZim'', [[OurVampiresAreDifferent Norlock]] points out that he and the Irkens can do this, since the humans are so oblivious they wouldn't be able to tell that they're real. It works.

[[folder:Films -- Animation]]
* In the ''WesternAnimation/{{TMNT}}'' movie, Michelangelo passes himself off as a ninja turtle impersonator by donning a large fake looking turtle head, and sticking a fake zipper onto his chest. No-one seems to take notice.
* In ''WesternAnimation/BatmanAndHarleyQuinn'', Harley has been keeping out of sight by [[FanServiceWithASmile working at a diner]] where the waitresses wear [[SexyWhateverOutfit sexy versions of superheroine/supervillainess costumes]].

[[folder:Films -- Live-Action]]
* In ''Film/TheIdleClass'', Creator/CharlieChaplin plays both TheTramp and [[IdenticalStranger a wealthy man staying at a resort]]. On the night of the MasqueradeBall, the rich man gets the visor of his suit of armor stuck. The Tramp then wanders into the masquerade ball and is taken to be the rich man disguised as a tramp.
* Similarly, in ''Film/LoveMeTonight,'' [[Creator/MauriceChevalier Maurice]] is a poor tailor who is believed by the local {{Blue Blood}}s to be royalty traveling incognito. For a MasqueradeBall, he wears his everyday casual suit, turtleneck, and flat cap.
* In ''Film/TheAddamsFamily'' movie, Wednesday declares that she is going dressed in her normal clothes as "a homicidal maniac" stating "TheyLookJustLikeEveryoneElse."
* The fourth ''Film/ScaryMovie'' has an alien (based on the "Billy" puppet from the ''Franchise/{{Saw}}'' franchise) who met his girlfriend at Mardi Gras, and defends his being there by saying that he "blended in."
* Agent Myers covers for ''Film/{{Hellboy}}'' and Sammael this way in TheMovie. "Great costumes, huh?"
* Inverted in 1992's ''Film/BatmanReturns'', in which Bruce Wayne and Selina Kyle come to Schreck's costume ball, as themselves (no costume). Despite this they accidentally revealed their secret identities to each other. In their minds, "Batman" and "Catwoman" are their true identities, with "Bruce Wayne" and "Selina Kyle" being the real costumes.
** Schrek accuses Bruce as coming dressed as a "trust-fund goodie-goodie." Later, when Bruce reveals himself to Selena, Schrek sees him and exclaims:
-->'''Schrek:''' Bruce Wayne!?! What are you doing, dressed as Batman?
-->'''Catwoman/Selena Kyle:''' Because he ''is'' Batman, you moron!
* Quasimodo gets to enjoy the Feast of Fools in Disney's ''Disney/TheHunchbackOfNotreDame''... up until the "unmasking". What came after that was a HopeSpot and then down, down, down, ''down''hill.
* In the sci-fi comedy ''Film/SpacedInvaders'', the titular Martians land in a small farming town on Halloween and are mistaken by most people for kids in costumes.
* In ''Film/IdleHands'' two undead teens turn up to the school dance -- one of them with the murder weapon still embedded in his skull. When asked who made their costumes, they give the name of their killer.
* In ''Film/ZorroTheGayBlade'', Don Diego attends a MasqueradeBall in his Zorro costume. At first the Aldante thinks he's caught Zorro, but then all the Dons (and later all the men invited to the party at all) show up in Zorro costumes, insisting they got a message from him telling them to do so.
* In flashback, the protagonist of the ''Literature/AnonymousRex'' TV movie recalls trying this as a kid, only to be dragged home by his father because his "amazingly realistic ''Velociraptor'' costume" drew too much attention.
* In ''Film/HocusPocus'' all the action takes place on Halloween. Therefore, the three witches are hardly out of place and move about the town freely. They even become the center of attention as the "entertainment" at the town's big costume party.
* Slightly parodied in the ''Film/{{Transformers}}'' movie when Sam is trying to find his [[MacGuffin Grandfather's glasses]] and the Autobots are walking around in the back yard. He tells the anxious robots to wait for him and stay low. A minute later he turns around and the Autobots have turned into their incognito alternate modes... parked in the back yard. Obviously they don't blend.
* Used hilariously illogically in ''Film/TheNeverendingStory 3''. Somehow, it's the first day of school, Chinese New Year, and Halloween all at the same time. The only reason why any of this happens is because the latter two events allow the fantastic characters to be out in the open.
* The opening of the film version of ''ComicBook/AmericanSplendor'' features this, as young Harvey Pekar is shown trick-or-treating as himself (he didn't believe in pretending to be something else). He doesn't get any candy.
* The main character of ''Film/OnceBitten'' doesn't realize that he's turning into a vampire and subconsciously dressing the part. When he attends a Halloween dance party, people guess by his choice of clothes that he's in a vampire costume, which confuses him.
* In ''Film/TwinFallsIdaho'', a girl convinces a pair of conjoined twins to attend a Halloween party as "Siamese twins." Everyone at the party assumes that it's just a costume.
* Spidey managed to play this off on an ordinary day in ''Film/SpiderMan2'', as everyone ''knows'' Spider-Man doesn't need elevators. What the guy thought he needed such a detailed and form-fitting costume for is another question. To be fair, though, they are in New York. The guy probably thought he downloaded the plans for a form-fitting, detailed Spider-Man costume off the Internet... just like people can do in the real world. There's an extended cut of the movie in which the guy ''does'' realize that it's the real Spider-Man. He reveals that he works for a marketing firm and that Spidey needs to do more with his image. He suggests a line of Spider-Man-branded cologne. That should be called [[MythologyGag Thwip]].

* One of the earliest [[TropeCodifier Trope Codifiers]] was Creator/EdgarAllanPoe's ''The Masque of the Red Death.'' In the story, a plague has swept the world and torn through the populace. A Duke ends up holding an extravagant party as the world dies around his estate, and locks the doors so no plague carriers can get in or out. Of course, when the Small Ben strikes midnight, [[ItWasHisSled it turns out that one of the party guests isn't wearing a mask after all, and is actually the personification of the plague.]] And [[KillEmAll then everybody died.]]
* ''Literature/{{Discworld}}'':
** In one of the early books, as an homage to ''The Masque of the Red Death'', a wizard who has just summoned Death is surprised to notice that, besides the usual outfit of cowl and scythe, he is also holding a cocktail sausage on a toothpick.
--->'''Death:''' (''defensively'') [[AC:I was at a party.]]\\
'''Wizard:''' Er ... was it a good party?\\
'''Death:''' [[AC:At the moment it is. I suspect it may go downhill rather quickly after midnight.]]\\
'''Wizard:''' Why?\\
'''Death:''' [[AC:That's when they think I'm going to take my mask off.]]
** In the later novel ''Discworld/{{Maskerade}}'', as well as the non-Discworld short story "Turntables of the Night", Death ''is'' wearing a cheap skeleton mask over his actual skull.
--->'''Death:''' [[AC:I thought I should get into the spirit of the thing.]]
** And then there's ''Discworld/WyrdSisters'', where Death takes the place on stage of an actor who was supposed to be playing Death... and then gets stage fright. As he points out, in his line of work, normally only one person sees him at a time. An audience is kind of new for him.
** Intentionally used by the Faculty of Unseen University, who don "False False Beards" -- little loops of wire over their ears and into their real beards -- to "disguise" them as people wearing very obvious false wizard-beards.
** Re-visited in ''Discworld/IShallWearMidnight'', when Mrs. Proust disguises Tiffany's genuine witch hat by sprinkling glitter on it and attaching an "Apprentice Witch Hat, AM $2.50" costume-shop label to its brim.
** In ''Discworld/WitchesAbroad'', Greebo is transformed from a nasty gray tomcat into a human so he can accompany the witches to the Samedi Nuit Mort masked ball. He chooses a ginger cat mask to wear ("Alwaysss wanted to be gingerrrr.")
** Also in ''Witches Abroad'', the witches are watching a parade with several dancers disguised as skeletons (all in black, with the bones painted on). As they share a bottle, Nanny Ogg passes it to the tall, skeletal figure next to her and remarks, "My, them bones is painted on good." A moment later she does a belated double-take, but by then Death has already moved on.
** In ''Discworld/MonstrousRegiment'', the heroes need to sneak into a heavily-fortified... um, [[DepartmentOfRedundancyDepartment fortress]]. Since the squad is comprised of [[spoiler:Girls pretending to be boys]], they take of obvious route of masquerading as "washerwomen". They get caught out by the guards because they are ''obviously'' [[spoiler:boys dressed as women]]. Which Tonker then debunks by [[spoiler:flashing the guards.]] Subverted by Lt. Blouse, who DOES get in, despite being [[spoiler:the ''only actual male in the squad'']], and hence the only one who is actually disguised as a female.
** Inverted in ''Discworld/{{Eric}}'', where Astfgl the King of Hell dresses in royal diabolic regalia of his own design... which is, basically, a kid's cheap Halloween devil-costume, complete with silly strap-on hornlets and a trident that keeps falling apart.
* In ''Literature/HarryPotterAndTheDeathlyHallows'', a Muggle child complimented Voldemort on his "costume" just before he murdered the Potters on Halloween of 1981.
* In ''Literature/GardensOfTheMoon'', the first book of the ''Literature/MalazanBookOfTheFallen'', many people in the streets of Darujhistan are impressed by the great Tiste Andii 'costume' Anomander Rake is wearing for Lady Simtal's party. The laquered dragon mask also turns out to be more of an injoke than a disguise, since he [[VoluntaryShapeshifting can turn into one]]. [[CrowningMomentOfFunny Alchemist Baruk called it, too]]:
-->'''Anomander Rake:''' As I understand such things, the event includes the wearing of disguises. Do you fear I lack taste?
-->'''Alchemist Baruk:''' I've no doubt your attire will be suitable. Particularly if you choose the costume of a Tiste Andii warlord.
* Used in some ''Literature/ForgottenRealms'' novels:
** Including Ed Greenwood's ''Silverfall'' (Qilue came round a masquerade "disguised" as "drow princess") and Elaine Cunningham's ''Daughter of the Drow'' (Dark Elves are stylish and thus a valid "costume"):
-->'''[[spoiler:Fyodor]]:''' You wish to join the festival, and slip into the city among the others... But what about your disguise?\\
'''Liriel Baenre:''' I'm a drow, of course. It's quite an exotic costume. And authentic, too!
** In Ed Greenwood's ''[[SideStoryBonusArt Ladies Night at the Yawning Portal]]'':
--->''Jalamra, Jalamra, [[SeenItAll have you not seen spell-spun illusions before]]? I ask you: just ''how'' would a band of no less than ''seven'' [[BrainFood illithids]], [[RefugeInAudacity walking along quite openly]] in their robes [[{{Cthulhumanoid}} with mauve tentacles a-slimily quivering]], manage to get right to the heart of Waterdeep? Next you'll be telling me th--...''
* In Creator/CharlesDeLint's ''Jack of Kinrowan'', a pink-haired fairy mentions that one reason she likes the modern era is that she no longer has to dye her hair.
* The fictional play ''Literature/TheKingInYellow'' features this scene. (The excerpt is found in "The Mask" by Robert W. Chambers.)
-->'''Camilla:''' You, sir, should unmask.\\
'''Stranger:''' Indeed?\\
'''Cassilda:''' Indeed it's time. We have all laid aside disguise but you.\\
'''Stranger:''' I wear [[TheBlank no mask]].\\
'''Camilla:''' (''terrified, aside to Cassilda'') [[HumanoidAbomination No mask?]] [[GoMadFromTheRevelation No mask?!?]]
* The protagonist of ''Literature/TheGargoyle'' enjoys the lack of attention his hideous burns receive during Halloween. Now, if only they didn't make his angel costume look so satanic...
* In ''Literature/AmericanPsycho'', serial killer Patrick Bateman goes to a Halloween party dressed as a serial killer, complete with real human blood on his suit.
* In Creator/TanyaHuff's ''[[Literature/BloodBooks Blood Lines]]'', vampire Henry Fitzroy goes to a Halloween party as Dracula. His partner is dubious, but Henry points out it's actually good camouflage--if he pretends to be a vampire on Halloween, obviously he isn't one the rest of the year.
* Although he does wear a costume, in ''ThePhantomOfTheOpera'' it is implied that Erik is not wearing a mask when he attends the masquerade as Red Death.
* In the book ''Literature/{{Beastly}}'' by Alex Flinn, a modern take on "Literature/BeautyAndTheBeast", the Beast, Kyle, attends a high school's Halloween party with regular clothes on over his fur.
* In ''Nightingale's Lament'', a {{Literature/Nightside}} novel, a singer eludes her rabid fans' attentions by stopping off at a nightclub where all the staff, and most of the patrons, are [[spoiler: drag queen]] impersonators of their favorite singing divas. She easily passes unnoticed in the crowd of Madonnas, Dolly Partons, and assorted Spice Girls.
* In ''[[Literature/WingsQuartet Wings]]'' by Aprilynne Pike, David helps make Laurel's wings look fake so she can be convincing at the school costume ball. Extra 'Awwwww!' factor for the cutesy line: [[spoiler: "I'll have to tell them only Laurel gets wings."]]
* Creator/MercedesLackey:
** Invoked and averted in the Literature/DianaTregarde story "Satanic, Versus..." The heroine considers going to a costume party with her boyfriend as a witch and a vampire--but he argues that there's no point in going as what they really are, and they dress as Series/TheAvengers instead.
** Played straight in one of the Literature/HeraldsOfValdemar novels. When catgirl Nyara goes into Hardorn with a covert team, she goes in disguise ... as a woman made up to look like a catgirl, complete with "seams" shaved into her fur and a set of absurdly large fake ears.
** Toyed with in the Valdemar novel ''Oathbreakers''. [[{{Ojou}} Lady Kethryveris of house Pheregrul]] rides into the capital of Rethwellan with a string of high-quality mounts for sale, obtained through her oath-sisterhood with Shin'a'in chieftain Tarma shena Tale'sedrin. While the preceding was completely true the two left out a few details (not least of which were the facts that House Pheregrul [[ImpoverishedPatrician had been on hard times for decades]] and clan Tale'sedrin [[LastOfHisKind had exactly two members, counting Tarma's oathsister]]).
* Used cleverly in the subversive children's novel ''Literature/JenniferHecateMacbethWilliamMcKinleyAndMeElizabeth''. Jennifer, a sombre, [[CreepyChild beautifully creepy]] Afro-American girl, wears authentic Pilgrim clothing to her school's Halloween party. She tells her friend Elizabeth that the real witches were Pilgrims, and that she herself is a witch who spends most of the year disguised as an ordinary schoolgirl; by dressing this way she is becoming undisguised.
* Played with in ''Literature/TheChroniclesOfVladimirTod: Eight Grade Bites''. Vlad, a vampire, goes to a Halloween party wearing plastic fangs and a cape.
* Spider Robinson's ''Literature/CallahansCrosstimeSaloon'' story "Unnatural Causes". An alien Krundai comes to Callahan's bar on Halloween night as himself (green, furry and pointed, over-sized ears).
* In the ''Literature/BookOfTheNewSun'', Severian attends a masquerade ball in his executioner's outfit, under the (correct) assumption that everyone will assume that it's a disguise.
* In ''[[Literature/LegendsOfLaconia Halloween Romance]]'', the two [[OurVampiresAreDifferent main]] [[OurWerewolvesAreDifferent characters]] meet while they are both doing this.
* In Creator/RobertBloch's "The Secret Of Sebek", some genuine occultists avoid persecution for their practices by hosting parties for dilettante spiritualists and psychic charlatans, ensuring their own ''genuine'' mystic rites will go unremarked-upon.
* ''Literature/TheDresdenFiles'':
** Played with when wizard [[FirstPersonSmartass Harry]] [[DeadpanSnarker Dresden]] goes to the Vampire's Masquerade Ball... dressed as a vampire. He is being deliberately insulting, and so dresses as the most cliche Dracula stereotype he can come up with; caked on white face paint, giant cape with a tall collar, fake blood around his mouth, the works.
--->'''Harry:''' Not only that, but a ''cheesy'' vampire.
** Played straight with his friend Michael, Knight of the Cross, who went dressed as a Knight Templar to the same party. The vampires thought it was a costume until one made the mistake of touching him and got burned.
* In Creator/BruceCoville's ''Literature/TheMonstersRing'', the main character twists the ring twice ("Twist it once, you're horned and haired;/Twist it twice, and fangs are bared...") shortly before the school Halloween party and let everyone assume the result was an incredibly good costume.
* In ''Literature/TheMoonMazeGame'', teenage Prince Ali of Kikaya participates in the titular LARP in the role of ... a young prince of Kikaya.
* Used twice in the eighth novel of ''Literature/WearingTheCape'', specifically in the story crossover with ''Webcomic/GrrlPower''. The straightest version is when Sydney (aka The Mighty Halo), main protagonist of the webcomic swaps her real gear for toy versions and a metal ring that appears to hold her orbs (which normally float above her head in a circle when not in use), to look like a Halo cosplayer while scoping the dealers room of a convention her team is attending. The second time is when Astra, main protagonist from the novels, arrives in Sydney's reality while in costume... where her and her team and their exploits are the subject of a superhero television show and she presumed to be someone cosplaying as the character at the same convention.

[[folder:Live-Action TV]]
* Used in a non-humorous way in ''Series/{{Angel}}''. One half-demon was kept trapped in his house by his mother growing up, because he looks hideous. The only time she ever let him outside was on Halloween.
** Averted in ''Series/{{Buffy|the Vampire Slayer}}''. Most demons don't like going out during Halloween because it's so commercialized and kitschy, and consider it the one day of the year they'd rather stay home.
*** Also inverted in the aptly named Season 2 episode "Halloween." Instead of monsters pretending to be normal people in costumes, normal people put on costumes... [[BecomingTheCostume and turn into monsters.]]
*** Inverted again with Oz, who dresses as his normal self for Halloween - but wears a name-tag that reads "God" ([[Recap/BuffyTheVampireSlayerS4E4FearItself "Fear Itself"]]).
** In Season 4, the Initiative walk around openly on Halloween in their soldier outfits. Buffy notices them and doesn't think much of it, until she encounters them later in the season.
** Lorne often pretends he's wearing a costume to deal with people's reactions to his green-skin & red horns. When he got a job as a singer in Vegas, all the dancing girls (The Lornettes) wore green makeup & red horns to match. Incidentally, we also learn that only one member of the Blue Man Group actually wears makeup.
*** There's also the episode where he pretends to be dressed up to read to the children when a case takes the group to a library. The librarian compliments him on his realistic mask, but points out that [[YourCostumeNeedsWork the horns aren't very convincing]].
* The leonine Vincent took advantage of this in one episode of the ''Series/{{Beauty and the Beast|1987}}'' series. Creator Creator/GeorgeRRMartin says that they hoped to do the same thing every season on an annual "Halloween" episode, but that didn't pan out.
* In a Halloween episode of ''Series/DarkAngel'', several of the cast (who were transgenic supersoldiers with barcodes on their necks) tried to pass for people dressed as... transgenic supersoldiers with barcodes on their necks. The response to the costumes varied, some were considered cool, others unoriginal, and some normal humans were using the same costume. The transgenics were actually what they were cosplaying as, and using it as a cover, but some were still told YourCostumeNeedsWork.
* ''Series/{{ALF}}'' did this one, too, with a zipper attached to his fur. It still left guests wondering about his height, though.
* ''Series/{{Farscape}}'' uses this one, when the aliens accidentally land on 1985 Earth. They use the [[ContrivedCoincidence fortuitous happenstance]] of landing there the night before Hallowe'en to disguise their alien-ness. It doesn't work so well...but a little bit of hallucinogenic dust goes a long way.
* Similarly, in a Halloween episode of ''Series/{{Supernatural}}'', the demon Samhain is able to walk around amongst all of the trick-or-treaters with no one taking notice of the injury he's sustained to his stomach, or all the blood that's seeping from it.
* Then Senator UsefulNotes/BarackObama pulled this on an ''Series/SaturdayNightLive'' [[http://www.hulu.com/watch/19048/saturday-night-live-clinton-halloween-party skit.]]
* In one episode of ''Series/SabrinaTheTeenageWitch'', Sabrina throws a Halloween party that gets crashed by monsters from the other realm. None of her high school friends think it's strange.
* This trope was used as early as the black-and-white TV show ''Series/TheMunsters''. During a Halloween episode, star character Herman Munster (who looks like a large Frankenstein's monster) dresses up as a knight to go to a local Halloween Party. During the costume contest, he removes the visor on his helmet, causing everyone around him to remark on how creative he was to "wear two costumes."
* Used in ''Series/{{The Flash|1990}}''. Almost everyone at the police costume party was going as The Flash despite the fact that nobody actually knew what he looked like beyond the red and gold blur. Naturally, when the real Flash showed up, his costume was deemed [[YourCostumeNeedsWork bland and unimaginative]]. Even the Trickster picked the wrong Flash, targeting Officer Murphy instead. The illusion crumbled when the real Flash used his powers.
* Played straight in ''Series/MightyMorphinPowerRangers''. Zordon's assistant robot Alpha Five loves Halloween because he can go mingle with kids as if it's just a costume. In one episode, Zordon specifically told him to go to the Juice Bar to look after the party guests, knowing that he wouldn't raise any suspicion.
** In the same episode, Bulk and Skull congratulate themselves on their "punk" costumes... which they don't seem to notice are made of their normal, everyday clothes.
** Also from that episode, the MonsterOfTheWeek (A FrankensteinsMonster, naturally). Including a [[Funny/MightyMorphinPowerRangers hilarious bit where a lusty teenage girl drags it off to the dance floor]].
* Not quite an example of this trope, but in one episode of ''Series/{{Poirot}}'' ("The Affair at the Victory Ball") Literature/HerculePoirot was supposed to go to a fancy dress party as a famous person. So naturally he went as himself.
-->'''Hastings:''' I still don't think they'll let you in; I thought I made it clear the Victory Ball is a costume do.\\
'''Poirot:''' Hercule Poirot does not wear costumes.\\
'''Hastings:''' Everybody does. The whole idea is to go as someone famous.\\
'''Poirot:''' [[FamedInStory Precisely.]]\\
'''Hastings:''' Oh. I see.
* In the episode "The Night the Cylons Landed" of ''Series/{{Galactica 1980}}'' the Centurion was mistaken for a guy in a Halloween costume.
** In ''Series/BattlestarGalactica1978'', the crew finally reaches Earth on Halloween, so everyone assumes they're regular humans despite their unusual clothes.
* Played ''not'' for laughs in an episode of ''Series/GreysAnatomy''. A guy with some facial imperfection tries to get [[TheCasanova Dr. Sloan]] to give him an operation as charity. On Halloween. His convincing line was ''On the way here, seven people have asked me what my disguise was about. So far.''
* Reference in one episode of ''Series/JudgeJudy'', wherein Judge Judy remarks (after scaring some common sense into a witness), "I don't need to dress up for Halloween, I just go as me."
* ''Series/{{Sanctuary}}'': When the Big Guy joins Henry to Comic-Con San Diego, Magnus comments it's "one of the few places he actually blends in".
* Played straight and subverted in an episode of ''Series/{{Friends}}''. Rachel and Joey both seemingly have forgone costumes. Rachel says that she is a pregnant woman who wants to wear her new dress because soon it won't fit anymore. The subversion is when Joey reveals that he actually ''is'' wearing a costume: he's dressed as Chandler.
* On the American version of ''Series/{{The Office|US}}'', Jim does this every Halloween. Generally, his costume includes things like taping three black circles of construction paper to his white shirt and claiming to be a sheet of paper.
* When ''Series/TheCape'' attended a costume ball in his full superhero regalia, not only did he successfully blend in, but he discovered that a character he helped in an earlier episode was also at the party in a knockoff Cape costume. He was flattered to have "a fan," although that's odd considering that he himself had adopted the identity of a preexisting comic-book character, so why would he think it was about him? Then again, the comic book didn't seem to be very well-known within the show's universe.
* The Halloween episode in the first season of ''Series/TheVampireDiaries'' had Vicki, just transformed into a vampire, coming to a Halloween party in a vampire costume. Later, Elena claimed that the blood on her costume was fake blood.
* Averted in the Creator/CBeebies series ''{{Balamory}}'' when Archie managed to persuade PC Plum to dress as a robot for the party, and not as a policeman. Again.
* Dicky in ''Series/NickyRickyDickyAndDawn'' went as himself to the school's Halloween Dance in "Scaredy Dance".
* In the ''Series/{{iZombie}}'' pilot, Liv attends a neighborhood Halloween party as a zombie, but she does add some "flesh decay" makeup to her face, since most people are used to seeing her normal "extremely pale with white hair" appearance and just assume she's emo or goth.
* UsefulNotes/RonaldReagan did this in a Halloween episode of ''Series/SpittingImage'', claiming there wasn't anything scarier than [[TakeThat a senile old man in charge of nuclear weapons]].
* Invoked in ''Series/TheMiddle'''s seventh-season Halloween episode when Axl's friend suggests that the mysterious trick-or-treater in TheGrimReaper costume they keep seeing might actually ''be'' Death, since Halloween is the one night of the year Death could walk around like that without anyone thinking anything's amiss.
* ''Series/{{Lucifer}}''. When Maze takes Trixie out trick-or-treating, the latter expresses disappointment that she doesn't have a costume as well. So Maze tells her to turn around, then drops her glamor to reveal a [[TwoFaced half-decayed face]]. Trixie is delighted with the result, to Maze's visible relief.
* Downplayed in ‘’Series/PeopleOfEarth’’, Don’s a HumanAlien but when he’s out in public he tries to dress like a fairly normal human, at a UFO convention he wears [[https://i.pinimg.com/originals/eb/c6/eb/ebc6eb29f9e95f0d9267ab97a5b97939.jpg the same outfit]] as on the ship, like the other White alien cosplayers.
* On ''Series/LegendsOfTomorrow'', the team travel to 1988 to help save a young Ray Palmer. At the conclusion, they show up in their full uniforms (including new member Zari in costume for the first time) to help the younger Ray trick or treating.

[[folder:Pro Wrestling]]
* Wrestling/UltimoDragon and Wrestling/ReyMysterioJr at ''Wrestling/{{WCW}} Halloween Havoc 1997'', the infamous event where the latter lost his mask to Wrestling/EddieGuerrero.
* In 2014 World Wonder Ring STARDOM adopted Fukumen's Mask Fiesta but since STARDOM ''isn't'' a lucharesu promotion, it was moved from July to October to be held alongside their Halloween party. This had the side effect of what few {{masked luchador}}s were present for the former keeping their regular masks for the latter.[[/folder]]

[[folder:Video Games]]
* In ''VideoGame/VampireTheMasqueradeBloodlines,'' a few [=NPCs=] mistake [[LooksLikeOrlok Nosferatu]] players for a body-modification buff... and one of them compliments you on the work done on [[PointyEars your ears.]]
** Of course, a few [=NPCs=] also assume that the Nosferatu PC's just wearing a mask: in a particularly amusing case, Venus politely informs the PC that there are no mosh pits in ''her'' establishment and redirects you to a DeathMetal show in a different club.
* In ''VideoGame/LeagueOfLegends'', [[MadScientist Dr.]] [[TheBrute Mundo]] has a skin, released as part of a Halloween-themed update, in which he is dressing up as [[http://img1.wikia.nocookie.net/__cb20101018194452/leagueoflegends/images/5/59/Dr._Mundo_MundoMundoSkin.jpg himself.]]
-->'''Dr. Mundo''': Mundo dresses up as himself a lot, or else he forgets. Has happened before.
* In ''VideoGame/SaintsRowTheThird'', when the Saints rob a bank at the start of the game, the Saints all wear Johnny Gat caricature masks, including Johnny Gat.
-->'''Johnny Gat''': Hell yeah! Who ''doesn't'' want to be Johnny Gat?
** In their defense, the Saints by this time have sold-out and become criminal celebrities; people robbing a bank in Johnny Gat masks wouldn't be that bizarre in-universe.
* During one mission in ''{{VideoGame/Dishonored}}'', Corvo sneaks into a masked ball by wearing his creepy assassin's mask, which is on wanted posters all over the city. He can even sign his own name on the guestbook. The other guests think he's some random gentleman who's trying to be funny. Considering the plague that's ravaging the city in the story, it may very well be a ShoutOut to [[Creator/EdgarAllanPoe Poe's]] ''Masque of the Red Death.'' The main difference is that Corvo's less about spreading plague and more about spreading horrible, horrible death to anyone who crosses him...[[FateWorseThanDeath or alternatively, something much worse.]]
* In ''[[VideoGame/SegaSuperstars Sonic & Sega All-Stars Racing]]'', everyone drives something related to their character. [[Franchise/SonicTheHedgehog Sonic]] drives a sports car modeled to look like him, [[VideoGame/{{Shenmue}} Ryo]] drives a motorcycle, the [[VideoGame/BonanzaBros Bonanza Bros.]] drive their getaway car, etc. However, [[VideoGame/FantasyZone Opa-Opa]], being a sentient spaceship, doesn't drive a car; he races with himself as his car.
** Similarly, in the sequel, [[VideoGame/NightsIntoDreams NiGHTS and Reala]] transform into cars ala their own games, although at least they have Nightopians and Nightmaren sitting in the driving seat. Also, there's [[spoiler: the equally-sentient AGES, a Creator/{{SEGA}}-themed robot that transforms between a Daytona stock-car, an ''VideoGame/AfterBurner'' plane, and a [[ConsoleCameo Dreamcast controller]] depending on the location]].
* Most people in ''VideoGame/{{Skullgirls}}'' know Eliza as a diva singer who happens to wear a very gaudy and revealing outfit. Less people (those people being Samson, Leviathan, and the Medicis) know that [[Really700YearsOld she's actually an ancient being]], and that outfit she wears is the same one she wore back in the game's equivalent to ancient Egypt.
* Genji of ''VideoGame/{{Overwatch}}'', ninja [[EmergencyTransformation turned into a cyborg to save his life]] after [[SiblingMurder his brother tried to kill him]]:
-->''My Halloween costume? [[CyberNinja Cyborg Ninja]].''
* The free RPG Maker game ''[[https://rabbitongames.itch.io/trickandtreat Trick & Treat]]'' is set at Halloween and features two girls dressed as a witch and a pumpkin maid. [[spoiler:The former is [[WitchSpecies an actual witch]] and the latter is a magically animated construct that the witch made from a pumpkin to use as her personal maid.]]

[[folder:Web Animation]]
* In the ''Machinima/RedVsBlue 2008'' Hallowe'en special, everyone dressed up as Caboose...including Caboose, who didn't know it was Hallowe'en.
* In the ''Machinima/{{Smashtasm}} 2010'' Halloween special, Super64 tells H and Lamp:
-->'''Super64:''' I've decided to dress up as myself for Halloween this year, as a reminder to kids everywhere to always BeYourself.\\
'''H:''' I hate you. I ''really'' do.
* ''WebAnimation/HomestarRunner'' goes to a convention cosplaying as himself, which, in this case, means wear a propeller cap ''over'' his propeller cap and taping a paper star over his red star T-shirt.
** Another episode has Strong Sad apparently entering a Strong Sad look-alike contest only for Coach Z to immediately disqualify him for that very reason. [[spoiler: Turns out it was actually Homsar in an ''EXTREMELY'' detailed and lifelike costume.]]

[[folder:Web Comics]]
* Averted with in [[http://www.brunothebandit.com/w/20000619.html this storyline]] of ''Webcomic/BrunoTheBandit'': The monsters visit a party disguised as humans.
* Played with in ''Webcomic/ZebraGirl'', where Sandra, a human trapped in a demon body, plans to go out undisguised on Halloween... until she suddenly finds herself back in her human form. Turns out demons become more powerful on Halloween, and she can thus change her appearance with illusions at will. She decides to go out as her ''human'' self, sans costume, because she probably won't get another chance to do it for another year.
* Webcomic/AbeAndKroenen take advantage of the local fan convention to walk around New York unhindered. Abe also suggests they do this when accepting trick-or-treaters to Kroenen's house--after Kroenen finally agrees to get into the spirit of things, he finds out Abe just wanted to use him and his horrifically mutilated face as decoration.
* Forcibly invoked (and subverted) in the webcomic [[http://www.krakowstudios.com/archive.php?date=20090528 Charliehorse]] when Preson suggests --in great detail-- that Charlie the succubus take the opportunity to attend a Halloween party as herself. [[spoiler:Turns out she'd rather go as Cinderella, instead.]]
* In ''Webcomic/{{Weregeek}}'', the hardcore geeks are safe from the Hunters on Halloween... a truce has been established, because the risks are too high; the hunters can't tell "real" cosplayers from those dressing up for the occasion. Hiding one's costuming hobby in a costume holiday!
* Grace of ''Webcomic/ElGoonishShive'' apparently [[http://www.egscomics.com/sketchbook/?date=2007-10-31 considered]] (off-continuity) the Halloween "costume" of a squirrel-girl with three tails and antennae. Also, [[http://www.egscomics.com/sketchbook.php?id=100 Liz]].
* Invoked in ''Webcomic/{{Misfile}}'' with Vashiel's brilliant idea to go as an angel. [[http://www.misfile.com/?page=1424 It's immediately shot down.]]
* As seen on their cast page, the creators of ''Webcomic/CaseyAndAndy'' once went to a Halloween party dressed as their webcomic selves.
* The title character in ''Webcomic/{{Terinu}}'' is a four and a half-foot tall alien with a seven foot long prehensile tail, gray skin and horns. He gets around because most humans assume he's a "moddie" with extensive plastic surgery and prosthetics, created for a sick wierdo's amusement. {{Squick}}
* In ''Webcomic/AMagicalRoommate'', Alexis and X always dressed as witches for Halloween. But after they ended up sprouting fairy wings on their 21st birthday, X's roommate Aylia suggested that they go as human-sized black fairies instead. X loved this idea, as the costume required zero effort on her part (In fact, it took less effort than her usual outfits, as she didn't have to conceal her wings).
* In ''Webcomic/GoblinHollow'', [[http://www.rhjunior.com/GH/00392.html the goblins come out at Halloween. It's covered]].
* In an ''Webcomic/ItsWalky'' Halloween strip, Joyce (dressed as a harlequin) chaticises [[UpperClassTwit Jason]] for not having his costume ready. He replies he's going as Film/JamesBond.
** In Webcomic/{{Shortpacked}}, Robin asks Mike (who has just learned that he's going to be a dad), what his costume is, as he is wearing his normal work clothes. He says his costume is "Father". Considering that it's ''[[MagnificentBastard Mike]]'' Robin concedes that this is pretty scary.
* In an early ''Webcomic/DragonCity'' comic, [[OurDragonsAreDifferent bipedal dragon]] Erin Parrity [[http://dragoncity.thecomicseries.com/comics/45/ goes trick-or-treating with some humans.]] Bonus points for not only not wearing a costume, but also not wearing anything at all.
-->'''Human kid:''' Oh wow! That's a neat costume!
-->'''Erin:''' Thanks. [[ExactWords My parents helped me make it.]]
* In ''Webcomic/WelcomeToChastity'' Mei goes to Rayya with strong evidence that their roommate, Gwen, might be a witch, Rayya tells Mei she's being ridiculous, only for Gwen to barge into room wearing a stereotypical witch outfit for the college Halloween party.
* In the ''Webcomic/TheWhiteboard'' Halloween party storyline in 2003, there's a [[TheCameo Cameo]] by [[Webcomic/SchlockMercenary Kevyn Andreyasn]], who's wearing his normal outfit from his "home" comic. He explains it as [[http://www.the-whiteboard.com/autowb218.html coming dressed as a clone of himself.]]

[[folder:Web Original]]
* Due to AppliedPhlebotinum, the superpowered Tennyo in the ''Literature/WhateleyUniverse'' stories now looks remarkably like Ryoko from ''Anime/TenchiMuyo''. Her roommate decided that the whole team would go to the [[SuperHeroSchool Whateley Academy]] Halloween party as Tenchi Muyo characters, with Tennyo as Ryoko. Given that these teenagers have superpowers, getting a Washu and even a Ryo-Ohki wasn't a problem.
* During ''Roleplay/InkCity'''s Halloween Party, [[VideoGame/{{Persona 4}} Souji and Yosuke]] dress up as their Personas -- a clever twist on the whole "Thou art I, and I am thou" concept. Not that they see it as so clever once [[WesternAnimation/MyLittlePonyFriendshipIsMagic Discord]] [[BecomingTheCostume turns everyone into their costumes]]...
* One of the many Halloween celebrations at ''Podcast/KakosIndustries'' featured a Halloween party with a demon theme. They even gave out a cool prize for the best costume. Then they gave it to someone who was actually ''wearing'' a costume. Corin apologizes to Balthazaar, but notes "you know how you look."

* ''WesternAnimation/{{Gargoyles}}'':
** The Gargoyles love Halloween for just this reason. The younger gargoyles, getting into the spirit of the holiday, wears actual costumes (such as a pirate outfit) and are complimented on wearing "a costume over a costume". Goliath, meanwhile, goes out as himself with Elisa (who goes as [[Disney/BeautyAndTheBeast Belle]], both as a ShoutOut, and because their relationship is also BeastAndBeauty), and apparently the fact that he's 6'10" passes unremarked upon as part of his "costume".
** When another Halloween comes around again in the comic book continuation, Elisa keeps a theme by being [[Disney/{{Aladdin}} Princess Jasmine]] and Goliath once again doesn't bother. Neither does Delilah, who, not knowing better, explains what she ''really'' is when asked; "dressing up" as a [[CloningBlues DNA mashup]] of both Goliath's ex and Elisa, his current love interest causes ''quite'' the awkward moment.
* ''WesternAnimation/AmericanDragonJakeLong'' has the episode "The Halloween Bash", where Jake throws a party for both magical and non-magical beings on Halloween. This trope is in effect.
* In ''WesternAnimation/AdventuresOfTheGummiBears'', the bears take advantage of Folly Day in Dunwyn, with two variants; the occasion takes place strictly in the day and at 5:00 pm there is the traditional unmasking which means the bears have a strict deadline to leave lest they be exposed. It fails -- Duke Igthorn and Toady sneak in disguise, spot Sunni and instantly recognize her as the real thing.
* ''Franchise/SpiderMan'':
** In ''WesternAnimation/TheSpectacularSpiderMan'' episode "The Uncertainty Principle," Peter gets caught in-costume at a Halloween festival as Spider-Man, so he goes with it and winds up getting compliments on how well he fills out his costume. This actually comes in handy later, when Peter being seen in public as Spider-Man is later shown as evidence that he ISN'T Spider-Man. And judging by her [[EarlyBirdCameo cameo]] at the same carnival, Black Cat likes the holiday too.
** In ''WesternAnimation/SpiderManTheAnimatedSeries'', Spidey is fighting the Sinister Six with his powers working inconsistently. He manages to convince Rhino that he is actually the Chameleon, and redirects TheBrute to attack a distant shadow that is actually his teammate Shocker.
** The short-lived ''The Adventures of the Spider-Man'' features an episode where Peter has no way of getting home without his identity being revealed (his head piece is gone but he still has his main suit on). He then gets spotted by a crowd of people who all shout out: "great costume man!". Conveniently it is Independence day and a huge fancy costume party is being held in the Star Junction, so Peter just blends right in to the crowds.
* {{Franchise/Transformers}} cartoons:
** In one of the early episodes of ''Anime/TransformersCybertron'', the Autobots worry about revealing themselves on Earth. Bud jokingly suggests they pretend they're cosplayers (as Transformers are basically urban legends). Cue communal sweatdrop when Optimus Prime actually takes the suggestion seriously, apparently not realizing that twenty foot robots cannot get away with pretending they are costumes.
** However, in the [[WesternAnimation/TheTransformers first-generation cartoon]] they did exactly that. In "Auto-Bop", when Tracks and Blaster are investigating a trendy New York nightclub, a patron is very impressed with their "outfits".
--->'''Clubgoer:''' Hey! Where'd you get those threads? [=SoHo=]?\\
'''Tracks:''' Cybertron.\\
'''Clubgoer:''' What's the address?
* The cartoon adaptation of ''WesternAnimation/{{WITCH}}'' tops the comic: the girls move around the city in the Guardian outfits, Nerissa doing the same, Phobos going around in his evil prince outfit, Matt turning into Shagon, and ''Cedric and Miranda going out in his slippery dippery long mover-man and giant spider forms respectively''. and the only attention he drawed was on how he filled the tail of his costume. The ''only'' attention they get are Cornelia's mother glancing at Hay Lin's '[[BreastExpansion endowments]]' and commenting "I didn't know Halloween costumes came with ''that'' kind of padding." and people wondering how many guys are inside Cedric's costume. ''Then'' they start battling, and everyone mistakes it for a show.
* A ''WesternAnimation/FamilyGuy'' Halloween Episode had UsefulNotes/BillClinton doing this.
* In ''WesternAnimation/WordGirl'', one of Becky Botsford's friends, Todd "Scoops" Ming, realizes that she may be the titular superhero, citing several reasons including "You dress up as [=WordGirl=] every Halloween!" When the Narrator reacts, Becky responds "Well, I already had the costume...." In addition, a support character, Violet, dresses as the titular character in the Halloween-themed episode "Tobey's Tricks and Treats", and is mistaken as the superheroine by Tobey himself.
* In ''WesternAnimation/AaahhRealMonsters'', the main trio of monsters went trick-or-treating without costumes. It was a rare occasion that they met humans and made no effort to scare. HilarityEnsues, however, when they confuse a human child dressed as a red bunny with Ickis...
** In another episode, the monsters attend a horror themed tv show where the audience members wore costumes. A parent even asks Oblina where she bought her "ugly wax lips," to which Oblina replies "darling, you do not ''buy'' ugly, you ''inherit'' it!"
* ''WesternAnimation/DarkwingDuck'':
** Darkwing once goes to a masquerade ball in his costume, and is frustrated by everyone telling him he couldn't pull it off. [[YourCostumeNeedsWork "The real Darkwing Duck is taller..."]]
** His rival Gizmoduck once attends a ceremony in his honor, full of fans in homemade gizmo suits... all of whom thought he is a dressed-up fanboy too. Bonus points for Launchpad being mistaken for the original by being the only one in a formal suit. Plus a random contrivance.
** In another episode, Launchpad spends a good amount of time agonizing over what costume to wear to a party, before announcing he is going as "a flying ace!" Darkwing starts to point out that that is the same outfit Launchpad always wears, but quickly gives up.
* In the ''WesternAnimation/{{Tutenstein}}'' episode "Day of the Undead," Tut walks among mortals on Halloween, impressing trick-or-treaters with how much his costume looks and smells like a long dead mummy.
* ''WesternAnimation/TheFairlyOddParents'':
** Cosmo and Wanda go undisguised to a comic book convention, saying that no-one would notice they were fairies, and would just assume that they are big-headed kids in costume.
** [[AlienAmongUs Mark]] goes to Trixie's costume party as himself with some encouragement from Timmy. Timmy's fairies do this again at the same party.
* Steve Irwin did this in the ''WesternAnimation/SouthPark'' episode "Hell On Earth 2006". At first, he was called out on being [[DudeNotFunny disrespectful because he had a stingray in his chest]]. However, when he confirms the's the real Steve Irwin, he gets kicked out for not wearing an actual costume.
* ''WesternAnimation/TheSimpsons'':
** Inverted in "Treehouse of Horror XX", in which Dracula, Frankenstein's Monster, a Werewolf, and the Mummy go out on Halloween, and are made fun of for having old-school costumes. As such, they dress up. So much for their original plans...
** In another "Treehouse of Horror" episode, someone dressed as a witch wins a costume contest at the city-wide Halloween party. But it turns out that she really ''is'' a witch, and she promptly gets disqualified for not wearing a costume. Due to [[TooDumbToLive the people of Springfield this way having pissed off a real witch, with magic powers and all]], it is only natural that now HilarityEnsues... [[spoiler:To be precise: she transforms everyone into the costumes they are wearing -- which means that this trope afterwards technically applies to ''everyone'' in Springfield.]]
* In ''WesternAnimation/WinxClub'', in the season two episode "Hallowinx," Bloom's classmate Mitzi has invited her and the Winx to a Halloween party. Since they know no one would believe they're real fairies, they attend in their fairy forms.
* The ending of the Sofia The First episode "Ghostly Gala" has Sofia share her Halloween party space with Sir Dax and the other ghosts, and everyone thinks they're animatronics.
* In an episode of ''WesternAnimation/CareBearsAdventuresInCareALot'', Funshine travels down to Earth in order to help a little boy. He wants to show him to his Mom, but Funshine explains that he'd prefer to only be seen by kids because "adults don't always understand." During a later scene, the boy's mother enters the attic before Funshine can hide himself. He successfully poses as a stuffed toy.
%%* ''WesternAnimation/AtomicBetty'' did this.
* In the ''WesternAnimation/XMenEvolution'' episode "Cajun Charm," the X-Men find themselves in the middle of [[CityOfWeirdos Mardi Gras in New Orleans]], while looking for Rogue, who's been kidnapped. A random person comes up to Kurt, who's in his X-Men uniform and not wearing his image inducer, and tells him that his ''costume'' is great. Kurt's response? "Thanks! They are one of a kind."
* ''WesternAnimation/TheLifeAndTimesOfJuniperLee'' averts this. Since a barrier renders all magical creatures invisible to normal humans, child monsters instead dress themselves as humans for Halloween.
%%* ''WesternAnimation/DannyPhantom'' double episode: "Reality Trip"
* ''WesternAnimation/MenInBlack: The Series'': In "The Jack-O-Lantern Syndrome", Halloween is a favorite holiday of aliens living on Earth, though instead of going as themselves, they often dress up as a different alien species.
** In "The Star System Syndrome", several "monstrous" aliens star in monster horror films using their real appearance, while the film crews believe that they're human actors under a ''lot'' of make-up. The Hollywood branch of MIB specializes in getting entertainment contracts for aliens.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** While he isn't trying to hide his identity from anyone, Spike the purple dragon preforms a literal interpretation of this trope as his [[YouMeanXMas Nightmare Night]] costume is... [[ShapedLikeItself a purple dragon]].
** Princess Luna, whose SuperpoweredEvilSide was the inspiration for Nightmare Night, {{Avert|edTrope}}s this when she visits Ponyville, as her 1000-year banishment made her unfamiliar with the custom of dressing as demons and monsters for the holiday.
* In ''WesternAnimation/DCShowcaseCatwoman'', Catwoman briefly pretends to be an exotic dancer in a Catwoman costume in order to get closer to Rough Cut.
* ''WesternAnimation/SabrinaTheAnimatedSeries'': Sabrina wore a witch costume.
* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'': Ever since Grim cut off Jack's head and Jack got a pumpkin for a replacement, Halloween was the only time of the year Jack could go out shopping.
* In Filmation's ''Batman'' animated series, the Scarecrow did this at the Halloween charity auction, hoping everyone would mistake him for the disguised Commissioner Gordon.
* An episode of ''WesternAnimation/{{Beetlejuice}}'' has B.J. permitted by Lydia to be seen in our world as a reveler as it's Halloween.
* Inversion: The WesternAnimation/BugsBunny cartoon "Hasty Hare" has Bugs coming across Marvin the Martian and K-9 and believing it to be Halloween. He gives them both trick-or-treat candy. (Whether or not it was Halloween is not relevant.)
* In the episode "Quintuplets" of [[WesternAnimation/PoundPuppies2010 the 2010 version of]] ''[[WesternAnimation/PoundPuppies2010 Pound Puppies]]'', Lucky, his team, and the adoptees were able to get into a Poughkeepsie Pups basketball game by he, Cookie, and Niblet dressing in human clothing and buying tickets. Lucky's team used the same tactic to get into an actual Halloween party in another first-season episode, "Nightmare On Pound Street".
* ''WesternAnimation/ShimmerAndShine'': Shimmer and Shine pass themselves as kids wearing genie costumes during a HalloweenEpisode.
* ''WesternAnimation/SuperNoobs'': The Halloween episode "Happy Noob-O-Ween" has aliens Memnock and Zenblock try to learn about Halloween by going [[ManChild trick or treating]] in their true alien forms and no costumes although some of their neighbors mistake their forms for costumes. Both Mem and Zen end up getting more than what they bargained for in terms of more than just candy through their alien identities and use of their battle balls.
* ''WesternAnimation/TheVentureBrothers'':
** In "Love-Bheits", the trope was [[ExploitedTrope exploited]] off-camera when the Impossible family won a Best Group Costume award as the Comicbook/FantasticFour. Since the Impossibles don't appear in the episode, it's a ContinuityLockout joke if you haven't seen enough of the show to know that they are in fact a direct parody of the Fantastic Four.
** An [[InvertedTrope inversion]] is [[DiscussedTrope discussed]] in "A Very Venture Halloween". Since Dr. Orpheus is almost never seen without his OminousOperaCape and MysticalHighCollar even in mixed company, wiseguy Dermott joked that on Halloween he expected to see Orpheus in sweatpants.

[[folder:Real Life]]
* According to others in the industry and frequent convention goers, [[Creator/ShinichiWatanabe Nabeshin]] has a habit of intentionally losing his translator escort in the crowds of fans, and then waiting in line to get in to his own panels. He of course does this when he, and dozens of his fans, are in full Nabeshin cosplay.
* In an interview, guitarist Music/{{Slash}} stated that he can go out as himself on Halloween, and someone even said "[[YourCostumeNeedsWork Hey, your Slash is pretty good, but I know someone with an even better one!]]"
* A bank robber who was nicknamed "the Gap-Toothed Bandit" for his resemblance to [[Magazine/{{MAD}} Alfred E. Neuman]] was arrested after going to a Halloween party dressed in the same get-up he wore on his robberies. [[TooDumbToLive And telling people he'd come "as a bank robber."]] Someone recognized him from his wanted poster and called the cops. Maybe he tried to deliberately invoke "YourCostumeNeedsWork" and failed.
* Sort of inverted by one of the few anecdotes in which someone got the verbal better of UsefulNotes/WinstonChurchill. Lady Nancy Astor, the first woman in Parliament, had invited him to a "fancy dress" (i.e., costume) party, and when he came by to RSVP the invitation, he wondered aloud "What should I come as?" She responded "Why don't you come ''sober''?"
* Teenage fashion blogger Tavi Gevinson admitted to breaking the "no Halloween costumes" rule at her suburban UsefulNotes/{{Chicago}} HighSchool and getting away with it because people had gotten used to her wearing outlandish outfits to school.
* Accidentally done by Creator/TimCurry. He decided to attend a showing of ''Film/TheRockyHorrorPictureShow'' and was kicked out because they thought he was a Tim Curry fan dressing up as him. Not helping was that there had been a problem with crazed Tim Curry fans during this time frame resulting from his portrayal in the movie.
* Creator/BryanCranston once went to ComicCon wearing a Walter White mask.
* UsefulNotes/BarackObama showed up on ''Series/SaturdayNightLive'' one Halloween...in a Barack Obama mask.
* Former Wrestling/{{WCW}} wrestler Glacier [[http://uproxx.com/prowrestling/2014/11/youll-never-believe-what-wcws-glacier-dressed-up-as-for-halloween/ dusted off his old costume for Halloween 2014]].
* Many celebrities like to go to Madame Tussauds and [[NobodyHereButUsStatues pretend to be the wax figures of themselves]] as a PracticalJoke.
* In a gag related to ClarkKenting, Creator/HenryCavill wandered around New York Times Square with massive posters advertising Film/BatmanVSupermanDawnOfJustice with his face on them, ''wearing a Superman outfit'', and no one recognized him. The only person who addressed him was [[CityOfWeirdos a shop employee asking him not to film there]].
