[[caption-width-right:282:[-What happens when your Fairy Godmother is a CosplayOtakuGirl.-] ]]

->''"Holy crudscones! Why am I in women's clothing?!"''
-->-- '''Sokka''', ''WebVideo/AvatarTheAbridgedSeries''

Some hapless character is swept off his/her feet by a {{cosplay}} enthusiast (or a whole bunch of them) and ends up wearing a new costume or disguise. Even if the outfit is extremely elaborate, the change looks [[ChangingClothesIsAFreeAction almost instantaneous]] to the audience, sometimes shortly hidden by a SmokeShield with the occasional FlungClothing.

In every case, the process is inexplicably too fast for the "victim" to even notice it happening until ''after'' they've been fully dolled up -- even if it includes lots of complex knots, several layers and/or ''a change of underwear'', and thus should have taken hours and lots of sweat and tears (not to mention any potential kicking and screaming by the victim in question) to put on.

This is loosely based on real-life situations where someone is usually shocked by how they look in a changing-room mirror; however, this trope does away with changing rooms and mirrors altogether.

Sometimes justified by the cosplay enthusiast using a [[MartialArtsAndCrafts weird martial art]] allowing him or her to undress and then dress the victim at high speed.

Less ludicrous if it is some magic-user using a spell to induce the sudden clothes change (as with the page picture) but [[AWizardDidIt that's just cheating]].

This is frequently the deed of a LovableSexManiac, and even when not the case, the clothes will commonly be some kind of {{fetish}} wear, like CatGirl, FrenchMaid, NaughtyNurseOutfit, PantyFighter, PlayboyBunny, [[GoGoEnslavement Slave Girl]], etc. -- [[DraggedIntoDrag even if the subject is male!]] Often an excuse for the artists to put the characters into some unusual costumes that they usually wouldn't be caught dead wearing.

Being knocked out and waking up in a weird outfit usually also counts. After all, dressing up someone unconscious isn't that easy either. Not to mention what it implies...

A variant exists when a person is expected to change clothes by him- or herself and is handled the outfit, absentmindedly dressing up. Again, just as implausibly, the reaction shot comes only after having finished putting everything on, up to the last button, as if the character just couldn't see what the costume looked like beforehand.

This trope is particularly common in {{Anime}} and {{Manga}}, where it is used for comedy and (of course) {{fanservice}}.

A subtrope of ChangingClothesIsAFreeAction. Compare InstantCostumeChange.

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* This happens a few times in ''Manga/RanmaOneHalf'', both the anime and manga:
** During the martial art skating match against the Golden Pair, Ranma-chan and Ryōga are swept away by the "Kolkhoz High Fashion Club" when the audience complains that Ranma's costume isn't sexy enough. They bring in portable booths as dressing rooms, but are quite fast to put Ryōga and Ranma into proper skating outfits.
** When Principal Kunō is teaching Akane how to swim, he promises a swimsuit which would allow her to "swim with the grace of a swan". She [[ImagineSpot imagines]] a beautiful ballerina outfit and goes to put it on. Next panel, it's actually a full-body suit making her look like an ugly duck, and she {{Megaton Punch}}es the Principal.
** A similar "dressing themselves without realizing what they're wearing" variant occurs to female Ranma. When trying to help a [[IllGirl sickly young boy]] who won't take his medicine unless she takes him on a date, she accepts the clothes he hands to her just to play along. It's only after she's dressed that she realizes she's wearing a SailorFuku blouse and [[FetishFuel gym bloomers]] (no skirt). She [[MegatonPunch kicks him out the window]] and calls him a {{Lolicon}}.
** The "martial art" variant happens later in the manga (Book #34). Happōsai is trying to force Ranma to wear a PlayboyBunny outfit, and after a SingleStrokeBattle, he manages to put a SailorFuku... on the ''male'' Ranma. Just as he's about to meet his mother to prove he was ''manly''.
** The trope could be said to be half-used during the fight against Ryū Kumon, where Ranma performs the Umi-Senken to remove Ryū's (and Sōun's) clothes in a blink. This one doesn't even need PowerPerversionPotential to be misapplied.
** A {{Filler}} scene in the very early anime implies that Nabiki keeps doing this to female Ranma when the latter's clothes are all in the laundry. Although the changes happen off-screen, Ranma keeps running in and out of frame wearing a [[WholesomeCrossdresser kimono]], a [[FetishFuel dominatrix outfit]], and even a Las Vegas-style showgirl outfit, complete with tiara and feathers, all while screaming at Nabiki to stop it.
** Being knocked out and waking up in a wedding dress/wedding kimono/wedding tux happens to Akane and Ranma twice each (and in Ranma's case, the tux ''and'' the kimono).
* ''Manga/MahouSenseiNegima'':
** The girls do this to Negi on several occasions. Most notably, at the Mahora Festival haunted house, they dress him as a [[WholesomeCrossdresser cute female kitsune]].
** There's also the distracted variant where Asuna and Setsuna get tricked into ''dressing themselves up'' in PantyFighter garb right before their tournament match, and not noticing what they were putting on until it was too late.
** This gets used a lot. Another example is in volume 4, when the cheerleaders don disguises in order to interfere with what they think is a date between Negi and Konoka. Misa and Sakurako end up in SailorFuku; Madoka is annoyed to find herself the "odd one out" in a [[WholesomeCrossdresser Chairman Mao suit]]. Lampshaded by the word "Transformation!" at the top of the panel, and by the price tags still dangling from the outfits. Extra points for Misa and Sakurako acquiring instant suntans into the bargain....
** [[http://www.mangafox.com/manga/mahou_sensei_negima/v05/c042/9.html Konoka drags Setsuna into a costume shop]]. She winds up in [[WholesomeCrossdresser Samurai garb]] to complement Konoka's [[{{Ojou}} princess outfit]]. [[http://www.mangafox.com/manga/mahou_sensei_negima/v05/c042/10.html It's really very fetching.]] Random people passing by thought they were a couple, leading to a [[http://www.mangafox.com/manga/mahou_sensei_negima/v05/c042/11.html rather "nice" photo shoot]].
** There's also the MaidCafe bit at the beginning of the festival arc. Granted, most of the girls dressed themselves, but you can see Akira is completely baffled as to why she's suddenly a bunnygirl. Mana is also surprised to suddenly be a miko (although Mana ''is'' a miko -- she's surprised to suddenly be dressed in the "porn" version of the uniform, especially as the clothes really don't look right with her height).
** Poor Ako gets knocked out and stuffed into a PlayboyBunny outfit and arranged into an interesting pose. Her friends snap the photo just as she regains consciousness, and "accidentally" email it off to Ako's crush, "Nagi", [[spoiler:who is really the ten-year-old Negi.]]
* ''Manga/GirlsBravo'':
** In the manga, LovableSexManiac Fukuyama pretends to be ill to trick {{Tsundere}} Kirie into various fetish wears, starting with a NaughtyNurseOutfit, then a {{Miko}} hakama, and finally a {{Meido}} garb. Every time, she complains about the costume only after being fully clothed. Though when Fukuyama shows he had plenty other cosplay outfits for her to try, she gets fed up and kicks him in the face.
** Which is only the first occurrence. Fukuyama is a real ''master'' at this, and keeps doing it to most off the female cast (though Kirie stays his favorite victim) again and again, going through about every {{fetish}} clothes imaginable.
* ''Manga/HayateTheCombatButler'':
** Happens to Hayate a lot. Usually he ends up dressed as a CatGirl, or something likewise highly embarrassing. This gets so bad that when Hayate admonishes Nagi for asking him to take off a costume he put on for her gets a ''negative'' response, she thinks she may have broken him. The reality is that he just doesn't want to [[UnsettlingGenderReveal reveal that he's actually a guy]] to another girl.
** Hinagiku also gets a taste of Instant Cosplay Surprise on her birthday thanks to [[ThoseTwoGuys the student council trio]]. She then has to unexpectedly perform karaoke.
* Averted (and maybe even subverted) by ''LightNovel/HaruhiSuzumiya'', in that getting Mikuru into a costume usually involves an extended sequence of Haruhi wrestling her down and stripping her (more or less offscreen).
* ''Manga/ExcelSaga'' manga volume 16 has Excel ambushed in a flagrantly [[LesYay yuri-tastic]] manner and stuffed into a ''[[Anime/FutariWaPrettyCure Pretty Cure]]'' outfit. Though it's mildly averted -- while Excel isn't particularly enthusiastic, she's more bothered by the fact that the costume isn't her ACROSS uniform. Also, the change in outfits is not an instant switcheroo; it's a multi-panel affair, complete with lines like "You must take off ''everything'' <3" and "Oh my, this is your real hair... it's so soft... to the touch..."
* In the ''Manga/LuckyStar'' OVA, Konata (already cosplaying as [[LightNovel/HaruhiSuzumiya Nagato's]] wizard costume from the NonIndicativeFirstEpisode) changes Kagami into a {{Meido}}, {{Miko}}, [[http://farm4.static.flickr.com/3222/2894425402_b267df7680_o.png Rin Tohsaka]], and [[http://anime2.kokidokom.net/wp-content/uploads/2008/10/lucky-star-ova-8.jpg Hatsune Miku]]. Can you resist the Grade S ZettaiRyouiki?!
* In ''LightNovel/{{Slayers}}'', at a point midway through the third season, immediately following a WhamEpisode where the party was scattered and unknown whether to be alive or dead. Lina wakes up wearing an ElegantGothicLolita costume. After several moments of gathering her thoughts and trying to figure out where she is, she finally notices, leading to an even split of mortification and all-consuming rage. The remainder of the episode plays out as an homage to ''Literature/AlicesAdventuresInWonderland'' (with [[EverythingsBetterWithPenguins penguins!]]), and at the end, she discovers that her outfit is an amusement park costume, receiving her regular clothes back in a dry-clean bag. However, the last line of the episode is her saying, "There's just one thing I haven't figured out. '''Who took off my clothes?'''"
* ''Manga/IronWokJan'': Jan, Kiriko, and Celine find themselves stuffed into pig costumes after accepting an invitation to a television cooking show (part of an attempt by StrawCritic Ohtani to humiliate the three chefs on multiple levels).
* Happens a few times in ''Manga/AiKora''.
** In chapter 15, Maeda convinces Sakurako to win money for a new air conditioner (and snap his buddy Shibusawa out of an obsession with ''moe'') by entering a MaidCafe's costume contest.
** In chapter 77, Maeda convinces Yukari to dress up in a cross between a SchoolSwimsuit and a PlayboyBunny outfit as part of a ploy to keep people from finding out [[ClosetGeek she's into video games]].
* In ''Manga/RosarioToVampire'', after Kokoa is turned into a little girl, the other girls take her shopping for clothes that fit. She is shocked to find herself cosplaying Arale from ''DrSlump''.
* ''LightNovel/OreNoImoutoGaKonnaNiKawaiiWakeGaNai'''s tenth episode features Ayase tricking her friend Kanako into cosplaying from a popular MagicalGirl show. Despite the costume design being a treasure trove of MagicalGirl tropes, Kanako only notices that it's "bratty anime crap" when she catches sight of herself in a car side-mirror.
* ''Manga/DNAngel'' has Daisuke's mom pulling this on him in the anime. Whenever she wants him to do a thief job he doesn't want to, she hands him a phone and while he's talking on it, she somehow manages to get him dressed in his thief clothes. Even more incredible that some of those clothes are pullover shirts, so how...? Naturally, Daisuke freaks out afterward but it's expected (sort of) since his mother was trained to be a master thief.
* ''Manga/{{Bleach}}'': This happens to Ichigo in one of the [[{{Anime}} New Year]] [[{{Filler}} specials]]. He's roped into helping [[OurWerewolvesAreDifferent Komamura]] and [[MamaBear Unohana]] make a film about a humanoid dog hero that saves lives, only to find himself forced to wear a badly designed dog costume. He's not amused.

[[folder:Comic Books]]
* [[http://scans-daily.dreamwidth.org/1346854.html A certain, legendarily strange Superman/Batman team-up comic]] has Franchise/{{Superman}} pulling this on Franchise/{{Batman}} and himself at the same time in reverse -- out of their costumes and back to normal clothing... in the time it takes Lois Lane to look to one side. Away from them, ''towards them''. Surprisingly played with just a hint of realism -- the speed is more than Bruce Wayne can take, resulting in him feeling highly nauseous and throwing up mere seconds later.
* In ''ComicBook/CableAndDeadpool'', there's a great scene where {{Deadpool}} wakes up very surprised to be dressed in an ComicBook/{{X-Men}} costume. {{Wolverine}} and Beast are standing nearby and note that they were betting as to whether Deadpool would hurl or think he was really on the team when he saw the costume.
-->'''Deadpool:''' (''slight smile'') I hurled.
[[/folder]]

[[folder:Fan Works]]
* In ''Fanfic/KyonBigDamnHero'', Kyon gains a sentient PDA he names Skynet. One of its abilities is that it lets any authorized user change Kyon's clothing. Haruhi uses this to scan pictures from the Internet, and makes Kyon cosplay in Victorian suits, along with Yuki in her ElegantGothicLolita dress.
* In ''Trixie: Behind the Curtain'', Trixie's portrayal of Rainbow Dash as the resident fashionista has her use high-speed flying to change her clients into new outfits faster than they can react.
[[/folder]]

[[folder:Films -- Animation]]
* ''Westernanimation/MyLittlePonyEquestriaGirls'':
** Human!Rarity pulls one on Twilight, putting her in a new dress and a blonde wig in a flash so that the student body wouldn't recognize and mock her any longer after the embarassing videos of Twilight show up on the Net.
** In "Shake Your Tail!", a short preceding ''WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks'', Pinkie Pie puts all her friends (and herself) in grass skirts and leis in a flurry of flowers, and they at first look puzzled by this.
[[/folder]]

[[folder:Literature]]
* This happens to Harry in ''Literature/TheDresdenFiles'' novel ''Literature/{{Changes}}'', when his literal faerie godmother alters his clothes several times before eventually settling on an outfit that, in Harry's own words, looks like "the Games Workshop version of a Jedi Knight."
[[/folder]]

[[folder:Live-Action TV]]
* Happens to the title character in ''Series/TheJohnLarroquetteShow'', who refuses to dress up for a charity collection... until MsFanservice [[FavoritismFlipFlop purrs like a kitten]]. [[GilliganCut Cue next scene]] and audience laughter as John Larroquette is standing there dressed like a duck.
* In the ''Series/{{Batman}}'' TV series, ToTheBatpole scenes have the dynamic duo in costume once they reach the batcave, no matter how they were dressed before (eventually revealed to be the result of the "Instant Costume Change Lever" on the wall.) In one episode, SelfDemonstrating/TheJoker discovers the Batpoles and slides down one. He is shocked, at the bottom, to find himself dressed as Batman.
* In one episode of ''Series/FamilyTies'', Mallory gets a job as a model. During a show, her father meets her backstage. He gets mistaken for a male model, forcibly re-dressed, and pushed out onto the stage.
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/BlazBlue'':
** Litchi repeatedly inflicts this on Noel in Noel's joke ending to ''VideoGame/BlazBlueCalamityTrigger'''s story mode.
** In ''[[VideoGame/BlazBlueContinuumShift Continuum Shift]]'', Tsubaki ends up as the victim of these antics instead.
* Near the end of ''VideoGame/SpaceQuest'', you must obtain an enemy uniform. To do this, you hide in the washing machine, and a Sarien comes in and turns it on, automatically changing you into the outfit.
* In the ''Anime/MaiHime'' doujinsoft game ''Fuuka Taisen'', one of [[BadassNormal Har]][[JokeCharacter uka's]] specials is a box where, if she grabs her opponent, will almost instantly change her (all the playable characters are female) into an anime character from another series. It doubles as a [[ActorAllusion Voice Actor Allusion]] because the character she changes them into are voiced by the same seiyuu (e.g., Mai, who is voiced by Creator/MaiNakahara, gets changed into Rena from ''VisualNovel/HigurashiNoNakuKoroNi'').
* In ''VideoGame/QuakeII'''s expansion pack ''Ground Zero'', towards the end of the game where you need to make the A-M Bomb, there's an area with a cylinder that, when activated and you step in, "dresses" you with a "Strogg Uniform" (the actual process seems to involve immersing you in some kind of liquid), allowing you to wander around the facility while the Strogg forces leave you alone (as long as you don't shoot).
* In ''VideoGame/TheLegendOfZeldaTwilightPrincess'', Link starts the game wearing clothes like those everyone else in his village wears. After he first ventures in the Twilight, is turned into a wolf, and eventually purges the Twilight from the area, he's turned back into a Hylian, now wearing the oh-so-familiar green clothes worn by his predecessor in ''Ocarina of Time'', much to his surprise.
[[/folder]]

[[folder:Web Animation]]
* It happens in a ''VideoGame/WorldOfWarcraft'' [[http://www.youtube.com/watch?v=iz-RmSG2s1k animated music video]] (at 2:30), where a pervert dwarf put a mage into woman's clothing during his sleep. Based on a French song by Richard Gotainer, "La Ballade de l'obsédé".
* The ''WebAnimation/BravestWarriors'' episode "Ultra Wankershim" has this done to Beth by the Emotion Lord, who has a new piece of Wankershim gear every time she's seen. She even lampshades it: "Stop applying clothes to me!"
[[/folder]]

[[folder:Web Comics]]
* In ''Webcomic/SparklingGenerationValkyrieYuuki'', [[http://www.sgvy.com/archives/Edda4/Issue5/Page5.html Loki goes the magic route]] to put Chiaki into a skimpy red bikini before commenting a Valkyrie battle sport-broadcast style.
-->'''Chiaki:''' Why am I dressed like this?\\
'''[[FourthWallObserver Loki]]:''' Gives the folks at home a [[{{Fanservice}} little somethin']].\\
'''[[TheDitz Chiaki]]:''' Oh! OK!
* In ''Webcomic/ElGoonishShive'', Ellen immediately notices the PowerPerversionPotential of Nanase's [[http://www.egscomics.com/?date=2008-06-25 clothing exchange spell]].
* Netta does this to Zip constantly in ''Webcomic/{{DDG}}''. It is probably easier if your victim is a [[OurSoulsAreDifferent disembodied soul]] contained in a magic cloak.
* In ''Webcomic/MegaTokyo'', Yuki's ImagineSpot about her friends learning that she's a MagicalGirl mimics this effect.
* In [[http://www.menagea3.net/d/20090813.html a strip]] of ''Webcomic/MenageA3'', although Zii and [=DiDi=] agreed to tries the various costumes, [=DiDi=] only reacts after being dolled up.
* Invoked by Mary in ''Webcomic/DubiousCompany''. The cast is stranded in an alternate dimension. The team brains cook up a spell to hop from dimension-to-dimension, ''Series/QuantumLeap''-style, in order to get back home. Mary modified it so they end up in the [[CostumePorn most fashionable]] attire for that dimension. [[RealWomenNeverWearDresses Tiren]] hates this.
* One of [[TheFairFolk Jareth's]] {{Signature Move}}s in ''Webcomic/{{Roommates}}'', for the geat annoyance [[http://asherhyder.deviantart.com/art/Roommates-116-Party-Hats-169674358 of everyone else]].
-->'''Javert:''' What have we told you about these unannounced wardrobe alterations?!

[[folder:Web Original]]
* This happens to Phase in the ''Literature/WhateleyUniverse'' at Halloween, just without the ''instant'' transformation. Phase is a teenaged boy who unfortunately looks like a really pretty girl. His team decides to go as the ''Anime/TenchiMuyo'' characters, since his teammate Tennyo looks so much like Ryoko to start with. At the last minute, he finds out his costume is... Tsunami. He's not a happy boy.
* ''Series/FlandersCompany'': Inflicted on the Flander's employees by Maxence and Déborah in episode "Bad Taste". Caleb ends up in a freaking chainmail, Hippolyte in a silly {{Hawaiian Shirt|edTourist}}, Dr. Parker... keeps his usual clothes, and Cindy is given a girly, colorful dress. The last part is actually the worst idea of the lot, as it is the barbarian girl's biggest BerserkButton. Carnage ensues.
[[/folder]]

[[folder:Western Animation]]
* In classic cartoons, this tends to happen as a "whirlwind" or as a "tear-away", and can even happen with one's own skin and fur.
* A similar situation happens in the ''WesternAnimation/CodeLyoko'' prequel, "XANA Awakens", when Odd, Ulrich and Yumi are virtualized for the first time and discover their [[DigitalAvatar Lyoko avatars]]. Odd, especially, is puzzled by his weird look:
-->'''Odd:''' Hey, That's not fair! How come he gets to be a samurai? That's so much cooler!\\
'''Jérémie:''' I have no idea why. Maybe the computer just reads into your own subconscious desires, and projects them onto your digital incarnation.\\
'''Odd:''' I don't dream about giant purple cats!
* The Genie from Disney's adaption of ''Disney/{{Aladdin}}'' sometimes does this to his friends. In [[WesternAnimation/AladdinTheSeries the television series]] he turns them into the cast of ''WesternAnimation/TaleSpin''. [[http://www.youtube.com/watch?v=CtBTLQYnZbo Seriously]].
* The first episode of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' has Rarity change Twilight Sparkle into a half-dozen outfits (ranging from formal wear to cosplaying as the Statue of Liberty) before the latter can break free. Most other instances of getting dressed up prompt this reaction as well, seeing as very few ponies wear clothes on a regular basis.
