An Alice in Wonderland costume logically requiring others doing the undressing is pointed out in Slayers. Given it was the standard for the theme park that Lina had been thrown into after a nearly disastrous confrontation with the Big Bad, one wonders why people would pay to go there.
Blood+ has Saya waking up naked after being captured (and rescued) by Solomon. Downplayed in that he gives her a nice gown to wear instead of something revealing.
Spoofed in the first episode of The Melancholy of Haruhi Suzumiya, where the narrator and cameraman Kyon nearly flips his lid when he realizes that Itsuki had to have undressed and bathed Mikuru while she was unconscious in order for the scene he was filming to make sense. He starts threatening physical violence as soon as it starts getting into "Dude, She's Like in a Coma" as well.
Tokiwa from Ask Dr. Rin! claims to attempt to do the lite version to Meirin, although all he actually tries to do is kiss her (even this fails). In fact, when he does make the claim, it more tends to highlight his own instability.
In the last arc of the Rurouni Kenshin manga, Enishi kidnaps Kaoru and uses her clothes to dress up a fake corpse that looks like her. Kaoru wakes up in Enishi's base in a bathrobe. He lends her a Western dressing gown later, though. This is made even more disturbing when you realize that all young women remind Enishi of his dead older sister.
Used in the second season, where Kallen is kept as a prisoner by Britannia for a good chunk of the season and wears a... rather revealing and frilly dress, as well as princess shoes (not to mention she's trapped inside a glass cage/room). She does get to beat up Suzaku while wearing it, though. A somewhat justified case, as she had been in ordinary prison garb (see C.C. below) in an ordinary prison cell, and her new accommodations were Nunnally's way of treating her nicely during her imprisonment.
Nearly happened to her in the first episode of the second season, where she's dressed up in bunny outfit while working undercover in a casino. A mafia boss at the casino is coincidentally going "bunny hunting" and tries to grab Kallen like he already had with a couple of other girls... Someone on the writing staff was given a little too much freedom.
Self-imposed version: C.C. spends much of the first season voluntarily wearing the full-body straitjacket Britannia stuck her in, symbolically representing her being bound to this world since, initially at least, she just wanted to die. As her interaction with Lelouch changes her worldview, she starts wearing more normal clothing, up until the final plot arc when the restraining suit makes a return to mark her willing participation in Lelouch's self-sacrificing Zero Requiem plot.
Used in the Magic Knight Rayearth anime, when the girls are captured by their rivals after losing to them in battle. Each girl wore typical costumes of the planets their captors came through: a Chinese dress for Fuu, a cyberpunk gown for Hikaru, and a revealing odalisque outfit for Umi. The latter even lampshades this when she openly whines to her captors, the Chizeta princesses, about having to dress in "skimpy" clothes (and how she's been putting on weight lately), but one of the princesses (Hot-Blooded Tata) shows surprise as to why Umi would complain. (To their captors's credits, they generally sent female guards or maids to greet the girls and give them these clothes; the only time it didn't happen, the one who dressed Hikaru up was a cute little boy).
Miyabi and Synclavia in Macademi Wasshoi weren't exactly modest when they were free (Synclavia's dominatrix outfit, especially), but after they're forced to work for Ataro, they're usually seen in some sort of otaku fetish outfit afterward. Meido wear is the most common, but they change according to Ataro's mood.
Played straight with a bit character in the first series; in the episode which flashes back to how Mao met Sōsuke and Kurz, the bad guys demonstrate their bad-guy status by, among other things, forcing a young female captive to wear first a bunnygirl costume and later a slinky dress.
Subverted in Full Metal Panic? Fumoffu—the villain of the day plans to do this to Kaname and Ren in order to torment Ren's father with pictures of it, but his compound is raided by Sōsuke and the Mikihara gang before he can put his plan into action.
The first instance took place when Evangeline kidnapped and brainwashed several of Negi's students. She dressed them up in French maid outfits before facing Negi.
Happens to Asuna Kagurazaka when the villain Wilhelm captured her, and she woke up in lingerie.
Happens again in the Magic World when the Gateport incident scatters everybody and Ako, Akira, and Natsumi end up selling themselves into slavery. Complete with French Maid Outfits (again) and shock collars. Negi and Kotarō are later able to buy their freedom.
Although the examples shown are usually not related to this trope, it should be noted that Negima often does show many people who are ready and willing to forcibly change another person's clothing and put them into various costumes (at Mahorafest for example, you are more likely to be press-ganged into a contest than you are to apply for one). This is usually Played for Laughs.
Nami in One Piece is captured by the creepy perverted Absalom that wants her as a wife and therefore wakes up in a gorgeous wedding dress. This temporarily distracts both Sanji and her would-be husband as they admire her (while she's still unconscious).
This is, well, the plot of He Is My Master—the whole series. Two girls become indentured maids to a kid, having no other way to repay the millions of yen they owe him; he spend the rest of the show dressing them up as embarrassingly as he possibly can.
In Episode 16 of Love Hina, Naru Narusegawa plays the role of Sanzo in a rather loosely-followed play of "Sayuki". In an opening shot, she is held captive on a chain leash by the "bad guy", and is wearing very similar clothes to slave Leia.
In Chapter 485 we see Tia Harribel in a skimpy outfit. She's a prisoner of the Vandereich and thus we see her in chains. Subverted in that the outfit is just her Resureccion Hollow Form, minus the BFS.
Female!Ranma is kidnapped by Sentarō Daimonji after she'd rescued him. The tea ceremony martial artist gives her drugged tea, and when she wakes up, Ranma is wearing an elaborate wedding kimono. Sentarō isn't really a villain, though, more like a clueless (if somewhat creepy) lovestruck teenager.
Later in the manga, Akane and Ukyō are captured by Konatsu's stepfamily of ugly kunōichi; they end up chained and dressed as Playboy Bunnies.
Another example is Mobile Suit Gundam ZZ when Leina Ashta is captured and held captive by Glemy Toto for most of the first half of the series. Glemy is enthralled by Leina and spends most of the time having her educated as a "Lady" to be an image in the future Zeon movement, much to her chagrin. During her captivity, Glemy has Leina wearing fancy dresses. In one episode she's also seen in a leotard while one of Glemy's instructors is giving her ballet lessons.
Hana, Katja's "soma" slave from Seikon No Qwaser is forced to wear a very stripperific cat costume that only covered her breasts and private parts when she was kidnapped by the Qwaser of Oxygen. She wears it again in a filler episode.
Katekyo Hitman Reborn!: While not quite as fanservicy as the trope usually implies, Daemon's first order of business after he pulls a Hypnotize the Princess on Chrome is making her change into the Simon Middle School uniform.
In Noein, when Haruka is abducted and taken to the future, she becomes naked except for a poncho.
In Märchen Awakens Romance besides the dog collar Alviss was forced to wear, he changed into a darker outfit when being controlled by Phantom.
In The Familiar of Zero, Luctiana kidnaps Saito and Tiffania. When the pair wakes up, they find that though Saito's outfit was untouched, Tiffania is now in traditional elf attire. At least it was a modest outfit.
In Campione!, Duke Sasha Dejenstahl Voban once had dozens of enslaved Mikos, who wore white tunics that exposed their arms, legs, and the sides of their torsos and they didn't have shoes nor underwear. In the present, he recaptures his former slave Mariya and she wakes up back in this outfit. This is anime-only, she was in her regular outfit in the light novel.
Rare male example: At one point in the comic Preacher hero Jesse Custer is knocked out and wakes up to find himself tied to a bed and dressed up in a World War II-era German officer's uniform. The culprit behind this is a villainess infatuated with Custer who also has a fetish for national socialist paraphernalia and a penchant for sadomasochism. Before she can have her way with Custer he frees himself and ties her up, prompting her to remark that she likes being treated in such a manner. While still in full Nazi getup, he encounters his black deputy. Awkward... (He looked like Claus Von Stauffenberg(the guy from Valkyrie) because he was wearing an eyepatch when he got up, which makes sense, as he was a worthy enemy in her eyes.)
Example for two genders: this Darker and Edgier comic series features the twins Wilykit and Wilykat, now hot teenagers rather than spunky children, dressed in very revealing clothing while they served as Mumm-Ra's servants. On the one hand, only Wilykit (the girl one) is actually referred in dialogue to as his concubine and is the only one shown bathing and dressing him... on the other hand she's actually referred to in dialogue as his concubine!!
Likewise Cheetara is chained to a pillar wearing a bikini made out of tattered rags, apparently having been handed over to the mutants. (The book takes place after a time jump — the specifics of how the characters got from their old status quo to the new one is glossed over.)
In Silver Surfer # 54-55, we see Thanos conquer the universe with the Infinity Gauntlet, and one of the first things he does is place his true love, the incarnation of Death, in a golden bikini.
The famous Dark Phoenix Saga of the X-Men comics had Mastermind brainwashing Phoenix into thinking she was his wife in the 18th century, and then had her dress up in a cheesy dominatrix outfit. Unfortunately for Mastermind, brainwashing is a risky business when the victim vastly outpowers you...
Early New Mutants issues see Dani Moonstar rendered unconscious, stripped and re-dressed several times; often by female villains. She even comments on it herself. "Man, I hope I'm not dressed this way for a party..."
This has happened to Storm as well, during an adventure in the Savage Land. It was possibly their first time there, but memory is sketchy since there's a 50/50 chance the X-Men will get captured whenever they go there.
A little over a decade earlier, we have a male example. In Havok's first appearance, he's kidnapped and dressed in an ancient Egyptian-style skirt by the Living Pharaoh in preparation for his upcoming sacrifice.
Another classic male example: In the first appearance of the Morlocks as a group, Angel was kidnapped on the orders of their leader, Callisto. He was dragged to the sewers of New York City, stripped to underwear, tied and with his wings skewered to a stand. He's later shown in obvious bondage gear for the "marriage ceremony." The entire situation is played for drama and taken very seriously by his fellow X-Men.
Starfire was captured and taken as a slave/trophy by the Gordanians prior to the formation of the team, and wore a militaristic black-and-metal outfit.
Her sister Komand'r wears the black suit with armor and cloak. Kory's original metal bikini is shown to be her slave harness, originally worn for working in a mine. She still wears a version of it, many years later.
In an issue of Thunderbolts, the supervillain Graviton takes over San Francisco and sets himself up as a conquering lord. When confronted by the protagonists, his "throne room" prominently features some captured female civilians forced to lie at his feet in bikinis.
Has happened to Caitlin Fairchild at least twice. The first time it's a mad scientist; the second (or at least a subsequent) time it's an alien warlord. Unlike most heroines, she actively dwells on the fact that this means the villain saw her naked.
In a borderline third case, she becomes indebted to a villainess who forces Fairchild to go on a mission for her in a fetishistic latex costume. She's not technically a prisoner (except to her debt and/or sense of honor) but at the end of the mission, the villainess erases her memory, leaving her thinking that she still owes a favor (and suggesting that this isn't the first time she's done it).
Lady Blackhawk was kidnap and brainwashed by super villain Killer Shark and even had her own super villain outfit, here◊, here◊ and here◊
Poor Big Barda went through this twice on her first meeting with Superman (post-mid-80s-continuity-reboot-wise). She gets captured by the New Gods villain Sleez, and as Superman arrives on the scene, he finds Barda all dolled and dressed up as a Go-go dancer and being psionically controlled to dance for Sleez. Superman gets captured as well, and as Barda's husband Mister Miracle arrives on the scene, he finds Superman and Barda being psionically controlled by Sleez into making a porno movie! To put this in perspective, even Darkseid hated Sleez; the reason he was on Earth in the first place was because he was kicked out of Apokolips by Darkseid for being such a creep.
Wendy: You murdered my boyfriend... destroyed my workplace... trapped Noser in a giant diamond... gave my best friend Lacey leukemia... and did God-knows-what to the only father figure I've ever known... and the worst you could think to do to me was put me in a slave girl costume?
Played with in a HomestuckKink Meme fic; the Condesce puts her slaves in acceptably modest outfits for their walks outside, but won't let them wear their personal symbols. For most trolls, this is an erasure of identity, and worse than being naked. Her latest slave has more mixed feelings about it because he shares the same symbol as his bloodlink, who is in cahoots with the Condesce and has done terrible things to him.
Films — Animation
Aladdin: Jafar makes Princess Jasmine wear a red harem outfit, although her normal clothes don't cover much more; they're just blue. Once he's defeated they turn back, confirming they were magical in nature.
This happens to Ginormica in Monsters vs. Aliens. Twice. Though, they hang a lampshade on it somewhat the second time. To be fair, the first time her ripped wedding dress wouldn't make for much concealment. Hell, that space outfit is prime fuel. It's certainly much more attractive than that ugly uniform she was wearing before.
Subverted in The Prince of Egypt. The Midian slave girl (Tsipporah, future wife of Moses) is ordered bathed (of course) and brought to him. When he walks into the bedchamber, what appears to be an enraged Tsipporah sitting on his bed is revealed to be a tied up servant, with the girl nowhere to be seen.
It's mentioned in a couple of the Expanded Universe novels that Jabba is considered a bit of a weirdo among Hutts (and in some cases, a pervert) for having what amounts to a fetish for humanoid females.
A little bit of Truth in Television occurred here, according to Carrie Fisher's DVD commentary. She claims it was the wardrobe designer's way of forcing her to exercise. (That was putting it nicely. She said in another interview that the incredibly uncomfortable outfit was "what supermodels would be wearing in the fourth layer of Hell".)
A combined parody/Homage occurs in the live-action Street Fighter movie. At one point, Chun-Li is captured by Bison and forced into an outfit that better suits his tastes. It's her outfit from the game series on which the movie is (rather loosely) based.
Inversion in The Curse of the Black Pearl: shortly after taking Elizabeth Swan as his prisoner, Captain Barbossa gives her a proper dress to wear. What she's wearing when captured is, by modern standards, a reasonably concealing nightdress — but for the time in which the film is set, she was essentially naked. Incidentally, the alternative was nudity — and a night with the crew.
Alluded to in Dead Man's Chest when she shows up at Jack's crew recruitment dressed as a man and reveals to him who she is.
"It should be a dress or nothing. I happen to have no dress in my cabin."
Played straight in At World's End: when Elizabeth impersonates an encarnate Calypso for Sao Feng, he dresses her in what we'll assume is the most queenly costume he just happened to have on his ship. Given how Barbossa came by the dress he gave Elizabeth in CoTBP, this has nasty implications.
Hannibal: Clarice is rendered unconscious by a gunshot wound and then kidnapped (or rescued, or maybe both at once, depends on your point of view) by the title character, and wakes up wearing an evening gown (specifically a Sexy Backless OutfitAbsolute Cleavage one) instead of the casual clothes she was wearing earlier. Which never happened in the book — although Clarice does end up wearing the evening gown, she's allowed to put it on without Lecter being in the room. Nor does Lecter ever undress her, except to tend her injuries.
Mortal Kombat, The Movie: Shang Tsung abducts Sonya Blade on the pretext of challenging her, rather than Liu Kang, for the final match. By the time Liu and Johnny Cage show up, Sonya has, for no readily apparent reason, been dressed up in an unflattering leather dress (which actually covers more of her than the tank top and shorts she'd been wearing up to that point), is barefoot, and her hair has been thoroughly teased.
Raiders of the Lost Ark: Belloq convinces his captive Marion to put on a fancy dress that he just happens to have with him.
In Dr. No, Honey Rider dons a pair of capri pants and a tunic-style top to attend a dinner with Bond, Dr. No, and company. After the dinner, Bond is beaten up by No's henchmen and Honey is dragged away; when next we see her, she's chained up in a flooding basin, still wearing the top but without the pants.
In the James Bond spoof Our Man Flint, when Galaxy agent Gila does her Heel-Face Turn, she is dragged away to be turned into a brainwashed Pleasure Unit. But before being sent to the actual brainwashing machine she's dressed in a red bikini.
Played straight in Taken, with an unpleasantly appropriate justification: The kidnapped women are being auctioned off as sex slaves.
Played for laughs in the '80s film The Night Before: Keanu Reeves' character accidentally sells his prom date to a pimp, and when he goes to rescue her later in the movie she's handcuffed to a bed in her bra and panties.
In Unlawful Entry, Madeline Stowe's character is forced to change into a blouse-and-slit-skirt combo by Ray Liotta's.
The 2009 Sherlock Holmes film features a male version, with Sherlock stripped and chained to a bed, though this was just to inconvenience him for a while rather than get any kind of sexual thrill.
In the 1993 thriller Kalifornia, the villain, Early Grayce (Brad Pitt), forces his female companion to wear a skimpy baby-doll dress at all times. Following the girl's Heel-Face Turn, Early murders her and takes the protagonist's female partner captive — and humiliates her by forcing her to wear the same skimpy dress.
In 28 Days Later, Major West dresses Hannah and Selena in fancy red dresses in preparation for mass rapes by the soldiers to "repopulate" after the virus dies out.
Male version in TRON: Legacy with Sam: the Armory Sirens cut his clothes off and he is quickly dressed in a black suit, complete with armor and Tron Lines, for competing in the Games.
Done in Knight and Day. Cameron Diaz wakes up on a desert island, finding herself in a bikini. Tom Cruise quickly informs her that being an expert bomb defuser, he could easily take her clothes off and change her into a bikini with his eyes shut. Not that that's what he did...
After the heroine is chloroformed and kidnapped by her stalker in P2, she wakes up wearing an Absolute Cleavage white dress.
In Perfect Strangers (2003), a man charms a woman into coming with him to his private island. While she's bathing, he throws all her clothes into the fire and leaves a translucent black dress with no shoes for her to wear, and she realizes she's been kidnapped. At the end of the film, after the man has died, the woman does a similar trick to another man.
When Pepper Potts is kidnapped during Iron Man 3, she's forced to wear nothing but a black sports bra and black pants.
Played with in John Carter: Dejah Thoris says that her revealing wedding dress is "too vulgar" for her tastes, implying she's being forced to wear it.
The Lone Ranger: After Rebecca and Danny are "rescued" by Cole, a maid dresses her in a fancy black gown and puts lipstick on her. Based on her reaction to seeing the lipstick on her wine glass, she's not comfortable in the outfit.
Largo Winch II: Malunai is forced by a Burmese general to wear an evening dress, which she keeps after Largo Winch frees her.
Slave World: Pretty much all british agents who gets captured, as well as most of the convicted serfs.
In John C. Wright's The Fugitives of Chaos, when Grendal captures Amelia, she wakes up in his mother's wedding dress. However, her captor Grendel is horror struck when she thinks he put her in it. He is a mass-murderer and dragged her off by force to marry her, but he wouldn't take off a girl's clothing when he wasn't married to her. He had his mother do it. (The dress also plays a significant role after her rescue.) Did we mention that the dress is see-through?
Male example: in David Eddings' The Belgariad, Garion is kidnapped by the decadent Queen Salmissra, drugged, and made to wear nothing but a loincloth. (Salmissra's female servants bathe and undress him.) It is clear that he is supposed to be a concubine, but his friends rescue him before Salmissra tries anything. And it is made clear that Garion is very disgusted by this when the drugs they give him wear off.
Amelia Peabody Emerson is captured by the Big Bad in Lion in the Valley and required to dress herself in a sexy harem costume. She keeps her long Victorian underwear on though. Husband Emerson is not appeased.
Subverted sickeningly in Under the Yoke when Sister Marya — a stocky and unattractive Polish nun — is made to wear a revealing silk nightie for the amusement of her masters, and of their guest who has asked their permission to rape her.
After a revolution turns Anchor Logh into New Eden in the Flux and Anchor series by Jack Chalker, the female half of New Eden's population is forced to wear the skimpiest clothing possible, as a reminder of their status and duties.
Happen to Lucilla in Daniel Gonzalez's Ravencraft in an alternate future chapter when Dracula rules the world and put her in a bikini and with a chain in her neck tied to his throne as punishment for been a vampire traitor. She also is tortured every night by Bathory in a BDSM-style.
Sort of an aversion, more of a slight variation really. In the Angel episode "Through the Looking Glass", Cordelia became basically kind of a cross between a Princess and a Sex Slave.
Sort of lampshaded when Cordelia talks about a commercial she'd been filming earlier, wearing a bikini.
Cordelia: They had me in this skimpy, exploitative (beat) nothing at all like this.
Also toyed with in a 6th season episode of Buffy the Vampire Slayer, when the Trio use some techno-magic to make a love-slave out of Warren's ex-girlfriend. The spell breaks though and she is understandably disgusted and enraged, pointing out that they essentially intended to rape her (which apparently never occurred to Jonathan or Andrew before that moment).
Casey is left handcuffed to a bed by Carina, a rival spy who doesn't play well with others. It's implied this isn't the first time she's done this to him. To be fair to Casey, she is a redhead. He escapes by breaking the bed, and has to wander the halls of a hotel in his underwear still cuffed to part of the headboard.
Happens to Chuck himself in a later episode. A spy pretending to be a naughty ("desperate," if you will) suburban housewife cuffs him to her bed (although she doesn't just ditch him — she intends to take him prisoner). He escapes and has to run across the cul de sac in his underwear with one wrist still cuffed.
Played with in LOST when Kate is captured by the Others. Mr. Friendly gives her a short dress to wear and takes her original clothing. She suspects that he is doing this because he wants to watch her change. It turns out that Mr. Friendly is gay, and the real reason he wants Kate to wear the dress is that Ben is trying to make Jack jealous by getting Kate and Sawyer together...
Happens to Guinevere in Merlin when she's captured by a local warlord.
The Mighty Boosh did the male variant of this, only played exactly like it would be with a woman. Howard is abducted by natives on the planet Xooberon, made the slave of The Chosen One, and forced to wear Leia-style chains and a sort of loincloth.
Happens in Power Rangers in one episode to Kimberly when Lord Zedd decided he wanted to make her his queen.
Sam Carter in the third episode, with the Mongolian warlords on another planet. It's implied that she did dress herself, though, which makes it less squicky. That one was also an example of "She Cleans Up Nicely".
Averted when SG-1 is captured and brainwashed by the Goa'uld Seth in the episode of the same name. Sam winds up wearing a concealing robe similar to that worn by Jack and Daniel.
While it's not quite the thing and says far more about Vala Mal Doran's dressing habits than Daniel Jackson himself, the latter has to remove the former's Kull Warrior armor and put her into SGC fatigues in the episode she steals the Prometheus. Her comment: "You've seen me naked, the least you could do is cook me dinner."
Played straight with Colonel Mitchell in "Memento Mori", in which SG-1 discover him chained to a bed, wearing only a blanket and eating snack cakes. He also seems to lose his pants often when imprisoned, which Sam Carter lampshades in the aforementioned episode.
Star Trek: The Next Generation has Data get kidnapped, and acid dumped onto his clothes in order to force him to wear a different outfit. Though it should be pointed out that the villain in question specified that the acid wouldn't harm Data's skin. The villain also specified that he'd be happy to have Data walk around naked, but he (correctly) assumed Data would be too modest to do so, and therefore supplied a change of clothing (the point of the acid was to get him out of his Starfleet uniform).
In Sliders, this happens to Wade Wells in Obsession (where the psychic in love with her makes her change clothes). It also happens to Maggie in Common Ground when a Kromagg commander falls in love for her, sort of, and makes her use a sexy red dress.
"The Squire of Gothos": Trelane uses his Reality Warper powers to change Yeoman Teresa Ross' uniform into a fancy gown, thus exchanging an impractically short skirt for a fine décolletage.
"Who Mourns For Adonis?": Apollo magically changes Lieutenant Carolyn Palamas' uniform into a pink peplos.
"Bread and Circuses": A female slave in a society similar to Earth's ancient Rome was at one point required to dress in a skimpy silver outfit. Kirk, Spock, McCoy, and the other prisoners had to wear grey uniforms.
The episode of Lost Girl taking place in Hecuba prison has all the (female) inmates, including Bo, wearing a tight red jumpsuit with a cut-out showing their cleavage.
Any adaptation of Flash Gordon is going to have poor Dale in a nutty Mongonian wedding dress for the scene where Ming tries to force her to marry him. Depending on the version of the story, she may be stuck in it for quite a while after Flash rescues her, until she has a chance to change.
For the final scene in The Phantom of the Opera, the Phantom has Christine wear a wedding dress. How exactly she got into it is never addressed.
In the film version of the same, the Phantom is seen sitting on his steps when Christine emerges from a side room clearly having just changed into the bridal gown. Murderous psycho, but he's a gentleman. This is yet another change from the original script, in which he tears her costume off of her—-prompting her query about whether he intends to rape her. Not until he has Raoul tied up and is threatening to kill him unless Christine complies does she put the dress on.
Games Workshop released a few models showing captured human women and Sisters of Battle in bikinis similar to the slave Leia one. Since their captors are the Dark Eldar, you can see where this is going.
Mentioned, but not shown, in Brutal Legend. The women of Bladehenge are kidnapped by glam rockers and forced to work in his "Pleasure Tower".
In Mortal Kombat, many of Shao Kahn's chained slaves can be seen wearing barely-there bikinis. Considering these outfits are strikingly similar to the outfits worn by every other woman in Outworld, it is implied that Shao Kahn is forcing every woman under his rule to dress like this (made especially evident when Kitana switches sides — and outfits — to join the heroes).
Male variation in Final Fantasy XII with Basch is shown in his imprisonment's "attire" consisted of a boxer, chain, crucifix and MORE chains. Fans have always wondered if it's that Gabranth just really hates him or has a fetish of torturing his brother.
Ninja Gaiden II (for the Xbox360) has Sonia dressed in a StripperificSpy Catsuit for the majority of the game, yet when she gets kidnapped by Alexei, she winds up in a diaphanous nightgown. Which turns out to be more modest than her regular garb.
Seth: I like the costume, Anna. Anna: So does Creon.
Fallout: New Vegas's Caesar's Legion is extremely misogynistic, as there are no female members. Instead, all of the camps have slaves, all female, wearing tightly cut rags. If the Courier is a female and joins the Legion, the uniforms are not very revealing: however, the slave cook warns her that she overheard some Legion soldiers talking about "trying you out". Nothing comes of this, although some soldiers can be very rude.
The slave outfits in the Fallout 3 DLC The Pitt, both male and female, consist solely of a harness and loincloth. By contrast, the slaves in the main game are more modestly dressed.
In the anime, Caster kidnaps the normally conservatively-dressed Sakura, brainwashes her, and dresses her up in a tight leather outfit that is quite out of character... Although it is a Shout-Out to the computer game on which the series is based, to a different plot scenario mentioned above.
Umineko: When They Cry: This is combined with I Have You Now, My Pretty with the infamous "Erika in a wedding dress" scenes. However, in this case it's inverted because even though Erika's in a wedding dress, she's the one doing the enslaving.
Laura in Collar 6, although this is a consensual case.
Domain Tnemrot: Many of the female slaves wear impractical skimpy outfits for fights.
In Freefall, Florence wonders about this when waking up in Mr. Kornada's pants. However, the reader knows that Sam had put them on her when she was wearing a hospital gown, to get her out of the building.
General Protection Fault: When Ki and Nick are first captured and employed by the James Bond-parodying secret agency the UGA, they are put into a skimpy bikini and a tuxedo respectively as their "uniforms".
KintheYuan-ti from Goblins is forced to wear nothing but a rag tied around her chest. After killing her captor she delays her escape to put on the most concealing coat she can. In so far as the trope normally involves the person continuing to wear the skimpy attire until the escape in complete, this makes it a partial subversion. See it here◊ and here◊.
Referenced in The Order of the Stick, when Roy accuses Nale of dressing up his (Roy's) captured sister Julia as "some faux-punk whore". Those are the clothes Julia normally wears. She is not pleased.
Played straight in Terinu when Gwen and Joleen held captive by the Ardactavians. In her case it's ostensibly to hide her in plain sight as a servant, due to her Cyber Glider abilities. Which would make sense, except that the Ardies are anthropomorphic bugs that are disgusted by mammals, so why would they have her show off even more skin than normal? Meanwhile, Terinu wakes up from being near mortally injured dressed in a much more modest open chested tunic and trousers, though there's some squick when you realize that the Gene Mage not only dressed him, but braided his hair with expensive jewels.
Humon plays with this in one stand-alone Niels comic strip. A random woman, presumably an agent or other enemy to his plans, wakes up tied to a chair while wearing a tasteful but strapless evening dress, opera gloves and fancy jewelry. She immediately starts freaking out, insisting that she wasn't wearing this earlier and wondering where her clothes are. Cue Niels, who appears in the doorway, wearing her clothes and jewelry under his suit jacket, remarking that he thinks the color suits him much better. Cue chibi-WTF-face from the woman.
Implied through Fridge Horror when The Nostalgia Critic is kidnapped by the Game Heroes to promote T-shirts. He's pretty shocked and confused over seeing that he's wearing a "Hero" T-shirt, so that logically means he was stripped while unconscious during his time there. And his "Th—they're treating me well" is Blatant Lies so...
Parodied in The Venture Bros., where team Venture is kidnapped on their way back from a costumed party. The theme they chose? Star Wars; and Dean was Leia.
Not explicitly pointed out, but in the episode "Mad as a Hatter" a woman kidnapped by the Mad Hatter is dressed as the title character of Alice in Wonderland. It becomes much creepier when you consider that the Hatter must have undressed her and put her in the costume himself. Of course, he may have simply hypnotized her into donning it herself with one of his "cards". Considering that the girl is actually Hatter's secretary, on whom he had a crush, and how the Hatter behaved towards her before he went bonkers, the second possibility isn't that far off.
There's actually an inversion in the series where The Joker seduces Dr. Harleen Quinzel, and she puts on a harlequin uniform, becoming Harley Quinn, then breaks him out of Arkham. True that Harley put that outfit on of her own free will, but when you think about it, that outfit represents the fact that Harley has become a slave to the Joker out of love. One thing's for sure, every villain in history that's tried to seduce the girl and failed would envy the Joker's success with Harley.
In "Baby-Doll", the actress who played Baby's teenage sister is kidnapped, knocked out, and wakes up in her old bedroom set... dressed in her old costume. Hopefully, Baby had her one henchwoman Mim dress "Sister Susie" instead of her two male thugs.
Maxine Gibson spends the Batman Beyond episode "Curse of Kobra, part 2" in a white Bare Your Midriff top and dress. Chances are that the two servant girls she subsequently beat up put it on her.
In the episode "Twin Factor" of Kim Possible, after being subjected to mind control under Dr. Drakken, Kim is seen wearing Shego's outfit. This is questioned and acknowledged by both Ron and Shego but quickly dismissed and never explained. Though a reasonable explanation can be drawn, like say Drakken ordering her to go into another room and dress up, leave it to the fans to take it a bit further. Since Shego made Señor Senior Junior and her entire enslaved population wear Shego's green dress (and the fact that Shego still wears her Team Go dress even while not part of their group), the whole logic about that dress just does not make any sense...
On Ed, Edd n Eddy, in their first encounter with the Kanker Sisters, the Eds wake up in the sisters' mobile home to find they're wearing bathrobes (that belong to the Kankers' fathers), and their clothes are hanging to dry outside. Again to be fair, it wouldn't be sporting of the Kankers to leave the Eds naked while their clothes were drying, although they are stalkers.
The Teen Titans cartoon features another example, this one with Robin. After he is blackmailed into becoming Slade's apprentice, the camera pans over Robin's outfit hanging on a hanger, then Robin donning the shirt of his new Slade-esque costume, then Slade stepping out of the shadows and nodding his head approvingly... implying that Slade was standing there the entire time, especially when one takes into account the extreme interest that Slade has for him. Though perverted interest or not, he'd be insane to let Robin out of his sight — it's Robin after all.
Danny Phantom, where Sam is forced to wear the pinkest dress she's ever had the dishonor of seeing to please her future hubby Prince Aragon in an Arranged Marriage. She subverts this later on by creating her own bridal dress as a plan to escape his clutches.
Happens to Sam again later, in a Brainwashed and Crazy fashion this time. The plant-ghost Undergrowth decides he likes Sam's nature-friendly attitude, and kidnaps her as his queen. The next time we see her, she emerges from a giant bud, dressed in leaves a la Poison Ivy.
In an American Dad! episode ("Tears of a Clooney"), Roger runs a vineyard in the back yard while Stan and Francine are out of the country, and adopts several foster children to work it. He gives two teenage girls to Steve as "personal assistants" and they're made to dress in exact duplicates of Leia's metal bikini, along with other skimpy outfits.
In the 4th movie, Into the Wild Green Yonder, the eco-feminist organization does this to this to the guys.
Zapp Brannigan: Ah, the fairer sex.
Zapp tries to do this to Leela the first time they meet, but she refuses to play along.
Korgoth of Barbaria: Korgoth in his travels meets a guy keeping a girl in a cage in his dining room.
Evangelyne from Wakfu, in the episode "Vampyro", gets mind-controled and kidnapped in preparation for becoming the host body of the Demoness Shadofang. Before the possession, she's put in a white Sexy Backless Outfit exposing the demonic marks that crept over her.
In the episode "Fun and Games" of Superman: The Animated Series Lois was knocked out by Toyman's gas, then later woke up in a doll's costume (no, not that doll). It was actually more concealing than her usual style, but considering Toyman's personality it was probably his equivalent of Chainmail Bikini.
In Dan Vs., episode "Dan vs. Technology", Elise tries to get rid of the proprietor of a computer company, but is then captured and put in an outfit similar to one from TRON.
Totally Spies!: In "Stuck In The Middle Ages With You" Clover is caught in a I Have You Now, My Pretty situation and is made to wear a pink princess gown and crown by a evil guy who wants her to be his "queen".
Subverted in Star Wars: The Clone Wars during the the comicbook adaptation Zygerian-arc. Ahsoka was disguised as a slavegirl and was given an outfit, that while a bit more modest than the one in the comics, it's still even more questionable than her first one, even if there was a Time Skip in the show.
Joan of Arc was charged by her captors with many things, including wearing men's clothes (a big no-no). They first forced a pledge from her not to wear men's clothes, then while she slept stole all her clothes and left a man's outfit behind. She was thus forced to wear that outfit and subsequently charged with violation of her oath. It's also been suggested that she was insistent on wearing men's clothing as a safeguard from her guards raping her. Many historians are of the opinion that when she was forced to wear women's clothing, she was actually raped.
One of several myths about Mata Hari (the Trope Namer for the Trope named after her) is that she was subjected to something like this for her execution. An issue of The New Yorker claimed that she was made to wear "a neat Amazonian tailored suit, especially made for the occasion, and a pair of new white gloves", but another account claimed that she wore the same low-cut blouse and tricorn hat ensemble which had been picked out by her accusers for her to wear at trial. However, neither account is consistent with the photographic evidence, and are likely false, especially considering that another myth claims she blew a kiss to the firing squad before the order to shoot was given.
