For [[{{Fanservice}} some reason]], some characters seem to walk around in a swimsuit, which may be [[JustifiedTrope justified]] because they work at a swimming pool or beach, or some other aquatic environment. They don't have to wear only a swimsuit; they can still wear other clothing as long as we see that there is a swimsuit underneath. For example, Misty of ''Videogame/PokemonGoldAndSilver'' wears a jacket and sandals, but we can see that she's wearing a swimsuit underneath. This trope is more often used by females, while males may have the WalkingShirtlessScene trope more, but neither one is gender specific.

Compare LeotardOfPower, WalkingShirtlessScene, UnderwearOfPower.

[[folder:Anime & Manga]]
* Yukimura Sanada from ''LightNovel/HyakkaRyouranSamuraiGirls'' wears a [[SchoolSwimsuit White School Swimsuit]] under her clothes. It's MUCH more apparent on her Master Samurai form.
* ''Manga/OnePiece'': Franky is a male example. Being a cyborg, it doesn't matter if he's ExposedToTheElements. His friend Kiwi of the Square Sisters does the same as well.
** Post-time skip, [[MsFanservice Nami]] runs around in nothing but a bikini top and low-rider jeans.
* ''Manga/KenkoZenrakeiSuieibuUmisho'' revolves around the wacky antics of a swimming club, so the cast is wearing {{School Swimsuit}}s most of the time. Amuro even wears a swimsuit under her school uniform so she can take a swim at any time -- [[InnocentFanserviceGirl when she's wearing anything at all, that is]].
* ''Anime/TengenToppaGurrenLagann'' has Yoko.
* [[Anime/MazingerZ Sayaka Yumi]] spends her day in ''Anime/{{Mazinkaiser}}'''s 4th OVA in a swimsuit not only on the beach, but an enemy's base because she's, well, [[DistressedDamsel kidnapped.]]
* Edolas Bisca from ''Manga/FairyTail''.
** Cana is usually in a bikini with pants and an occasional jacket.
** Lucy and Erza too, during the Tenrou Island arc.
* ''Anime/StrikeWitches'' has Yoshika, Mio, and Junko, all of whom wear {{School Swimsuit}}s underneath their uniform tops. [[RunningGag And no pants]].
* ''Manga/MedakaBox'' has Kikaijima Mogana, which makes sense because she's on the swim team. However, it's more of a security issue than it is one of practicality.
* As a member of the Swimming Club, Shirley from ''Anime/CodeGeass'' gets a few of these in her SchoolSwimsuit.
* In the ''VideoGame/GodEaterBurst'' spinoff manga ''The Summer Wars'', Alisa is tricked into wearing a bikini on a mission by another God Eater, Gina Dickinson. She's rather annoyed when she finds out (mostly because she felt embarrassed about baring so much in front of [[TheHero Yuu]], despite her normal {{Stripperiffic}} outfit...).
* Shura from ''Manga/BlueExorcist'' is always wearing a bikini top and short shorts.
[[/folder]]

[[folder:Comic Books]]
* OK, it's not a swimsuit in the traditional sense, but Series/WonderWoman has to count. And Wonder Woman's swimsuit showed much less flesh than her normal costume.
* Tigra of ''ComicBook/TheAvengers'' is a CatGirl (though of the "covered in fur" type, not the "human with cat ears and tail" type) superheroine whose "costume" is a black bikini, sometimes with toothlike trim or a tiger-head amulet as a clasp in front.
* ''{{Sub-Mariner}}''
** Namor wears a black bodysuit on the rare occasion when he feels an ounce of humility, but he's mostly known for going around in nothing but a green speedo. Somewhat justified by the fact that he spends most of his time underwater, but mitigated by the fact that (1) he wears it on land too, even in frigid climates, and (2) the vast majority of his fellow Atlanteans cover up quite a bit more.
** Namor's two [[DistaffCounterpart distaff counterparts]], Namora and Namorita, fight crime in a black one-piece and a green one-piece or bikini, respectively. When Namorita changed her name to Kymera (and her skin to blue) she adopted an odd [[http://www.thephoenixxx.com/jeangrey/heroines/kymera.jpg bikini/netting/seashell ensemble]].

[[folder:Films -- Live-Action]]
* Many FanService Extras in the ''Film/JamesBond'' films. (Commonly included in any list of "Bond Girls", but BondGirl refers to characters with actual personalities and prominent role in the movie.)
* In ''Film/LocalHero'', Marina, a marine biologist, wears a black one-piece under her lab coat at a facility -- justified as she has to do some equipment maintenance at the bottom of a large water tank. The visitors are quite distracted [[http://www.youtube.com/watch?v=VhrbGTv1PpQ]].
* ''The Bikini Car Wash Company''
* The female characters in ''Film/IntoTheBlue''.

* There are couple of them in ''H.O.T.S''. In the [[http://www.youtube.com/watch?v=OqdVrdTLUGU#t=20m24s first one]], The top to Boom Boom Bangs' bikini [[WardrobeMalfunction comes off]] when she jumps out of a plane to skydive into the H.O.T.S.' pool and gets blown offcourse, landing in the dean's pool instead. In [[http://www.youtube.com/watch?v=OqdVrdTLUGU#t=26m58m the second scene]], the [[AllGuysWantSororityWomen Pi sorority]] are all sunbathing at their house and 3 of them are topless when Mad Dog and O'Hara fly over the house in a hot air balloon to bombard them with banana cream pies.{{NSFW}}
* In ''The Young Nurses'', boat racer Donovan is shot on his boat, falls overboard and he nearly drowns. Nurse Kitty jumps off her boat performs, swims over to his boat and she performs first aid on him. She assists the paramedics and she's still only wearing her bikini when she rides in the ambulance with Donovan When bikini-clad Nurse Kitty arrives in the emergency room, she's chastised by Nurse Dockett (the head nurse) for the way she's dressed:
-->'''Nurse Dockett''': Nurse, where is your uniform?\\
'''Kitty''': I'm off duty now.
-->'''Nurse Dockett''': And on display!
* Bridgette is wearing a pair of shorts and a bikini top while washing [[AutoErotica her sex van]] in [[http://www.nitrovideo.com/video/hot-times-at-montclair-highvideo-clip-07-68710.html this scene]] in ''Hot Times at Montclair High''.

* ''Series/BlueWaterHigh'' is set in a surf school, so the main cast spends much of the series in swimsuits.
* Lila Archer in the ''Series/CriminalMinds'' episode "Somebody's Watching", where she does this ''twice''. The first time it's on the set of her TV series, "Emotional Cages", which is a drama about beach volleyball (the premise being picked obviously as an excuse for Archer to walk around in a bikini, just so Reid knows how attractive is the girl that's interested in him). The second time is when Reid is assigned to defend her at her house, where she decides to make a move on Reid, taking off her robe to go for a swim in a [[BlackBraAndPanties black bikini]] and pulling Reid into the pool and making out with him.
* Reporter Anna Gilligan throughout [[http://www.youtube.com/watch?v=nuAWGjJKw0I this segment]] on ''Good Day America''.

[[folder:Video Games]]
* Felicia from ''VideoGame/{{Darkstalkers}}'' technically counts as she walks around in naught but a FurBikini, and a real one would have covered her more.
* Misty from ''[[VideoGame/PokemonRedAndBlue Pokémon Red, Blue]],'' ''[[Videogame/PokemonGoldAndSilver Gold, and Silver]]'' and their remakes. An odd case, since she just wore swimsuits prior to the {{Timeskip}}. Possibly because an eleven-year-old walking around in a swimsuit is more innocent than a teenager doing so.
** Marlon from Black 2 and White 2 is a male example,also Mr.Fanservice.
*** The player characters of Black 2 and White 2 are visibly wearing swimsuits under their clothes. Nate is wearing a wetsuit, and Rosa is wearing wetsuit bottoms with a halter-style bikini top.
* ''VideoGame/ArcanaHeart''
** Kira Daidouji, because she fights waist-deep in a blob of water.
** Her rival, Catherine Kyohbashi for no reason whatsoever.
* Rikku from ''VideoGame/{{Final Fantasy X2}}'' wears a bikini with a miniskirt and a scarf over it as her default outfit.
* A Non-{{Fanservice}} one: In ''VideoGame/MySims Agents'', Clara Belle, Taylor, [[AllGuysWantCheerleaders Summer]] and [[SurferDude Luke]] wear some Beach-Wear (though Summer is a lifeguard).
* ''[[VideoGame/DeadOrAlive Dead or Alive: Xtreme Beach Volleyball]]''
* Justified with Trauare Wrede in ''VideoGame/{{Rosenkreuzstilette}}''. Due to her status as the game's [[MakingASplash Water-element boss]], she wears an open jacket over her swimsuit, and, well... not [[{{Stripperific}} much else]]. [[{{Fanservice}} It's as hot as it sounds.]]
* ''VideoGame/RumbleRoses'' the girls have scenes of them in swimsuits, and they also wrestle in them in mud wrestling.
* Numerous games in the ''{{Tales Series}}'' have swimsuit costumes for the entire party, allowing you to invoke this at will.
* ''VideoGame/{{Persona 3}}: FES'' and ''Portable'' have swimsuit costumes you can get for most of your party members, letting them storm the heights of Tartarus in bikinis and trunks. They're actually decent armor, but the normal gear already available by then often outperforms the swimsuits so you'll often end up putting them on once for a lark and then returning to the useful stuff.

[[folder:Real Life]]
* During their car wash fundraisers, many [[TheCheerleader high school and college cheerleaders]] often wear either bikinis or shorts and bikini tops.
