Walking Swimsuit Scene

""The Cederville Warriors was hosting their annual car was on the far edge of the parking lot. All the girls were in tiny shorts and bikini tops. Someone's car stereo was playing some terrible top 40 bubblegum crap, The girls were using the hose on each other, almost completely ignoring the gold Suburban they were supposed to be washing.""

- Nick Burd, The Vast Fields of Ordinary

For some reason, some girls seem to walk around in a swimsuit only for Fan Service, which may be justified because they work at a swimming pool or at the beach.

These girls 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 Pokémon Gold and Silver wears a jacket and sandals, but we can see that she's wearing a swimsuit underneath.

Advertising

 * Tab Cola commercial.
 * Sea and Ski Baby Oil commercial.
 * Mandalay Bay commercial.

Anime & Manga

 * It's the rare shonen anime that doesn't have a Beach Episode, a Hot Springs Episode, or both, getting the girls into their swimsuits (at the beach) or into towels or less (at the hot springs).
 * Yukimura Sanada from Hyakka Ryouran Samurai Girls wears a White School Swimsuit under her clothes. It's much more apparent on her Master Samurai form.
 * One Piece
 * Franky is a male example. Being a cyborg, it doesn't matter if he's Exposed to the Elements.
 * Kiwi of the Square Sisters and some of the Kuja, like Sandersonia and Daisy, are straight examples.
 * Kenko Zenrakei Suieibu Umisho revolves around the wacky antics of a swimming club, so the cast is wearing School Swimsuits most of the time. Amuro even wears a swimsuit under her school uniform so she can take a swim at any time -- when she's wearing anything at all, that is.
 * Tengen Toppa Gurren Lagann has Yoko.
 * Sayaka Yumi spends her day in Mazinkaiser's 4th OVA in a swimsuit not only on the beach, but an enemy's base because she's, well, kidnapped.
 * Edolas Bisca from Fairy Tail.
 * Cana is usually in a bikini with pants and an occasional jacket.
 * Lucy and Erza too, during the Tenrou Island arc
 * Strike Witches has Yoshika, Mio, and Junko, all of whom wear School Swimsuits underneath their uniform tops. And no pants.
 * Medaka Box 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 Code Geass gets a few of these in her School Swimsuit.

Comic Books

 * Tigra of The Avengers 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—in fact, until the 90s or so, it was the only thing he ever wore, and (2) the vast majority of his fellow Atlanteans cover up quite a bit more.
 * Namor's two 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 bikini/netting/seashell ensemble.

Films -- Live-Action

 * Many Fan Service Extras in the James Bond films. (Commonly included in any list of "Bond Girls", but Bond Girl refers to characters with actual personalities and prominent role in the movie)
 * In Local Hero, 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.
 * The Bikini Car Wash Company
 * The female characters in Into the Blue.
 * Lindsey Vuolo wears a monokini while telling a dirty joke in National Lampoon's Dirty Joke. (NSFW)

Live-Action TV

 * Every female character on Baywatch, ever. Justified for being Lifeguards and all.
 * The Miss America pageant's swimsuit competition.
 * Every lead female character on Saved by the Bell ends up doing one of these at least once.
 * Heather Thomas in the first episode of The Fall Guy - and then repeated in the opening credits of every single episode thereafter, for obvious reasons.
 * This was something of a standard trope in the 1970s and 1980s; if the cast of a series (sitcom or detective/action mostly) had a sexy female member, odds are are least one episode would find an excuse to get her into a swimsuit, either for a contrived beauty-pageant plotline (i.e. The Bionic Woman) or by finding an excuse to get them next to a swimming pool or on a cruise ship (i.e. Wilma Deering in the cruise ship episode of Buck Rogers in the 25th Century).
 * OK, it's not a swimsuit in the traditional sense, but Wonder Woman has to count.
 * And Wonder Woman's swimsuit showed much less flesh than her normal costume.
 * Male version on Buffy the Vampire Slayer as the girls discover Xander has joined the swim team. When he sees them ogling him he goes into a horrified crouch and covers himself with a paddleboard.
 * Reporter Anna Gilligan throughout this segment on Good Day America.
 * Male version in the "Schmitts Gay Beer" sketch which has speedo clad hunks on Saturday Night Live.
 * Cheryl Ladd in "Angels In Paradise" which is the second season premire epidode of Charlies Angels - and then repeated in the opening credits of every other episode thereafter, for obvious reasons.
 * This South Florida reporter wears a thong bikini while doing a story on Haulover nude beach. She also takes off her top at the beginning of the segment.

Music

 * "Itsy Bitsy Teeny Weenie Yellow Polka Dot Bikini" by Bobby Darin.
 * Faith Hill mentions men wearing speedos and women wearing bikinis in "Sunshine & Summertime" in the line "You'll see rock hard bodies and bikini hotties".
 * Carmen describes a bikini that "contains less cotton than a medicine bottle". No word on how much spandex though.

Video Games

 * Misty from Pokémon Red, Blue, Gold, and Silver and their remakes. An odd case, since she just wore swimsuits prior to the Time Skip. Possibly because an eleven-year-old walking around in a swimsuit is more innocent than a teenager doing so.
 * Arcana Heart
 * Kira Daidouji, because she fights waist-deep in a blob of water.
 * Her rival, Catherine Kyohbashi for no reason whatsoever.
 * Rikku from Final Fantasy X-2 wears a bikini with a miniskirt and a scarf over it as her default outfit.
 * A Non-Fan Service one, In My Sims Agents, Clara Belle, Taylor, Summer and Luke wear some Beach-Wear (though Summer is an Lifeguard).
 * Dead or Alive: Xtreme Beach Volleyball
 * Justified with Trauare Wrede in Rosenkreuzstilette. Due to her status as the game's Water-element boss, she wears an open jacket over her swimsuit, and, well... not much else. It's as hot as it sounds.
