Going Commando

"I'm not wearing underwear today No I'm not wearing underwear today Not that you probably care Much about my underwear ''Still nonetheless I gotta say: That I'm not wearing underwear todaaaaaay!"

- Avenue Q

Simply put, a character isn't wearing underwear for some reason. According to The Other Wiki, "'Going commando' is reputed to have begun with commando and other special forces military units, in which some soldiers stopped wearing underwear to prevent chafing."

When a male does it, it's generally played for humor, squick or he's wearing a kilt, in which it's known as "Going Regimental". When a female does it, it's usually treated as Fetish Fuel.

If a character is Going Commando solely for Fan Service purposes, it is often Vapor Wear.

Compare Naked in Mink, Diamonds in the Buff.

Not to be confused with the second game in the Ratchet and Clank series, or Stephen Colbert's week in Iraq.

 * Brooke Shields had a famous commercial with the statement "Nothing comes between me and my Calvin Kleins".

Anime & Manga
"Calumon: Calumon, zoom zoom, here a zoom, there a zoom! Calumon, zoom zoom, NO UNDERWEAR, ZOOM!"
 * Mello in Death Note has slits down to... well, you know in some official artwork
 * In Kono Suba the audience sometimes gets a shot of Aqua's butt, a significant amount of which is either bare or covered by a semi-transparent part of her skirt, and she appears to not be wearing any panties. There is an image of her in one of the novels that is now considered non-canon in which her panties are visible.
 * In Sora no Otoshimono, anime and manga, Sohara goes around like that for a whole episode/chapter. Against her will. She's also unable to wear any underwear... anything whatsoever in fact... and if she tries it flies away. Literally. That's just the kind of show it is. Never give magic powers to a perverted protagonist.
 * Happens to the heroine of Ghost Talker's Daydream. One of her day jobs is as a columnist for a porn magazine (the other is as a dominatrix at a BDSM club) and at one point she's reminded that the prize that the magazine is supposed to send to a reader is her panties. Since she hadn't brought spares, she leaves the ones she was wearing. Obviously played for Fetish Fuel since, a few minutes later, she stumbles on her high heels and falls down, giving a male witness an unobstructed view of her pantiless crotch.
 * Early in Dragon Ball, Goku once removed Bulma's panties while she was sleeping (and freaked out because she had no balls like his grandpa) and she remained unaware of it. When Muten Roshi asked to see her panties in exchange for his Dragon Ball, she lifted her skirt in front of him. It was only after she and Goku returned to their capsule house that she realized she had been going commando since the previous night, and it only got worse for her when she realized what Roshi really saw. She let Goku have it upon finding out that it was he who took them off.
 * Maria from Sayonara, Zetsubou-sensei does this constantly. Doesn't wear shoes or socks either. Though in her case it's more from innocence than sexuality.
 * In one episode, all the girls are wearing Kimonos and Maria is squirming uncomfortably. Someone asks why. She says that "she's been forced into wearing some". People assume she means underwear, but no, she's referring to socks.
 * Kanzaki Kaori from A Certain Magical Index wears no undergarments whatsoever (bra, panties, or socks).
 * ... and in A Certain Scientific Railgun, Kiyama Harumi wears a bra but no panties.
 * Plus there was one time Kuroko teleported off Mikoto's undergarments.
 * One episode of Grenadier had Rushuna get her panties shot off. The poor girl ended up running around the battlefield with her hand on her crotch while wailing "NOOOOO!!!" (Bad enough she ran out of ammo before it happened.)
 * In the manga version, she didn't seem to mind much, and quickly forgot about it. With predictable results.
 * One chapter of To LOVE-Ru had Yami accidentally cut Yui's panties off, forcing Yui to go commando for the rest of the day.
 * In One Piece, Franky's speedo was stolen by the crew in order to make him join. It didn't work...that is, until Robin stepped in. Eeeeeeeew.
 * Mahou Sensei Negima: Jack Rakan can steal the panties of all of Fate's minions except the dragon girl Tamaki. Guess why?
 * According to Akamatsu himself, Tamaki goes commando because her tail makes panties very uncomfortable for her, so she decided to just be practical about it. As a matter of fact, her entire race goes underwear-less for this reason.
 * Sometimes Asuna is prone to end up like this as well, with her being the indirect culprit. When she's hit by spells of any kind, her clothes go poof.
 * If this is any indication, Kaede doesn't wear panties when she's in her ninja getup.
 * Seen earlier: this shows Kaede removing her training garb to get in the "hot tub" with Negi.
 * Neon Genesis Evangelion has the pilots commando when in their plugsuits. Confirmed in the first Rebuild movie.
 * Actually confirmed in the series itself.
 * Godannar also has the pilots commando when in their spandex piloting outfits. Confirmed in the last few episodes.
 * In Bubblegum Crisis: Tokyo 2040, the Knights Saber are at first commando in their plug suits. Later, they don't even get plugsuits and are naked under their upgraded power armor (which is now transparent in places). Lampshaded by Sylia when she tells Mackie that "he's in the girls's changing room" when they're discussing it, and a totally flustered Mackie runs away all red-faced.
 * Great Teacher Onizuka: At one point, Fuyutsuki's panties are stolen by three students, who then spread the word that she isn't wearing underwear.
 * Natsuki Kuga from My-HiME had to go commando once because all of her underwear was stolen. Then a Dramatic Wind blew when she was talking to Takeda...
 * Mamiko Kuri from Narutaru never wears panties. She's also not a big fan of clothes in general.
 * While Aki Honda does wear panties normally (as far as we know), one of the worst manga scenes in regards to her has her panty-less (only in a skimpy and short white top and black stockings) while lovingly straddling an older boy. Who is her older brother Yasuhito.  In the anime this was bowdlerized: she was wearing a knee-length pink nightgown and a pair of brown tights.
 * Aruka Schild from NEEDLESS. It's even Lampshaded in one episode preview.
 * Female haibane from Haibane Renmei can't wear bras because of their wings.
 * Abe Takakazu from Kuso Miso Technique isn't wearing anything under his overalls.
 * At least one of Tao Ren's outfits in Shaman King would imply this, as the placement of a set of holes in the sides of his pants would normally reveal SOME form of underwear.
 * Female fans of Raideen like to debate whether Demon Prince Sharkin is going freebird under his very short, divided leather kilt. When gaps appear between the leather strips, you can tell he's definitely not wearing boxer shorts.
 * In Digimon Tamers, Bridge Bunnies Riley (Reika) and Tally (Megumi) find Calumon running around the control room. And then...

"Chinatsu: The first job I ever did with Shisho, the target's house was on the far side of a river. Skulking around in wet undies felt gross. So I snuck away and took them off. I hit everything I aimed at that day. I even shot better than Shisho did. He complimented me for it. Koko Hekmatyar: (snicker) Y-you're a better shot without underwear? (snort) Chinatsu: That's right. Koko Hekmatyar: Bwa ha ha! That's a great story!"
 * Yamada does this on purpose in an early episode of B Gata H Kei.
 * The Fan Service(ier) episode of Strike Witches has one character with missing panties turn into a Panty Thief. It cascades into people stealing the Panties of another character and in the end leaves multiple characters running around like this with lots and lots of Censor Steam included.
 * A chapter of Nana to Kaoru has Kaoru making Nana walk around the park without any underwear on. He has to jump through hoops making sure nobody encounters her while she's doing this.
 * Hatsukoi Limited special is about Andou Soako going through an entire (school) day without her undergarments, and trying to keep anyone from finding out.
 * In a post-chapter omake strip in Rosario + Vampire, Catgirl teacher Shizuka is asked what her bra size is. She replies that she doesn't wear one. Which become increasingly evident in later chapters.
 * The rather Fanservicey episode 8 of Macross Frontier has a Ridiculously Cute Critter run off with Sheryl's panties by accident while she's showering at school, and given that she's currently the hottest Idol Singer in the entire galaxy at the moment, causes a few issues with every single male student (except three) chasing after the Panty Thief to get the prize, seemingly with more desire to get it as treasure than to return them to her. Meanwhile, Plucky Girl Sheryl grabs Power Armor and rampages across campus to get them back. In a skirt. A Magic Skirt as the implication of Sheryl chasing her panties in a skirt is this trope.
 * Arcade Gamer Fubuki. Fubuki had to go through this trope when her panties were stolen in episode two.
 * Teenage hit-woman Chinatsu from Jormungand never wears panties to a fight, which comes as a shock to most of the rival characters who often don't notice until they're in the middle of a pitched gun battle. She does, however, have a good excuse for it...

"Aira: (holding a scythe to Nowa's throat) You're such a wild girl... you're not even wearing underwear. Leina: S-She doesn't?!? Nanael: Elves are really nasty bitches, too..."
 * Nowa in Queen's Blade doesn't wear underwear. She lives with elves, who don't do much better - their usual underwear is a pair of crossed leaves. Echidna, meanwhile, only wears a snake along her lower body - and when her lower half's off-camera, she likes to wear it on her shoulders instead...


 * In Baccano! several of the female characters wear pretty low-cut clothing (for the standards of the time), and almost none of them seem to have anything on underneath.
 * Merle in Escaflowne. Then again, she is a Catgirl, and with that tail of hers it'd be hard to put on ANY kind of panties...
 * Ooga, one of the Stalker Trio in Mitsudomoe gets so upset at the object of her affections apparently liking panties more than anything she immediately takes hers off, kicks them into the stratosphere, and swears to never wear them again.
 * Run in A Channel discovers she accidentally forgot to put socks on both feet, while bending down to take the one sock off, Tooru, standing behind her, discovers Run forgot something else too.
 * Shino and Aria of Seitokai Yakuindomo often go commando. This is generally played for laughs.
 * Maicchingu Machiko Sensei often goes braless, as evident by the number of pranks her students play on her which ends with her shirt removed and her breasts exposed. This was a kids' show, by the way.
 * According to an Eyeshield 21 Omake, Otawara spends less than half of an average day wearing underwear because he forgets to put it back on while changing for practice.
 * In a Tengen Toppa Gurren Lagann High School AU manga, Nia goes commando in a skirt. May be justified, due to her being a Cloudcuckoolander.
 * Kirika Misono from Eiken doesn't wears panties, of course this isn't the first thing you'd notice about her.
 * Fujiko of Lupin III spends almost an entire episode without underwear, or much of anything on, really. Somewhat odd in that this is one of two second series episodes directed by Hayao Miyazaki!
 * Mayumi in SHUFFLE! found out the hard way that flinging her clothes where she can't find them is a bad idea. She only got her panties back later that evening.
 * In Hekikai no AiON, Seine spends half the 5th chapter without panties because those were her only pair and got ruined. She also seen to use no bra.
 * Chii in Chobits is naked when she's first picked up by Hideki. He gives her his own clothing immediately and is given 'hand me downs' from Miss Hibeya but she's definitely lacking underwear. Buying her some is the plot of an entire episode. The fact that she has no clue what a bra is is brought up later. In the manga when she gives Yumi her work uniform she's noticeably topless. This was Bowdlerised in the anime to where she's finally wearing a bra.
 * While excised from the anime for obvious reasons, Rider from Fate/Zero was noted in the Light Novels to have a habit of prancing around the house while wearing neither pants nor underwear.

Comics
"Bystander: Son, I wanted you to learn about the female body; I just wish your first sight of it wasn't twenty feet wide."
 * In the 25th issue of Thunderbolts the team has to deal with a base filled with 25 supervillains. To be able to move around more freely, they ambush a small group, including female villain Joystick, and steal their costumes, leaving the stripped villains lying in a heap. One of the 'Bolts comments that when she wakes up, Joystick will probably wish she was the sort of person who wore underwear.
 * The main character of Empowered discovered early in her career that if she wears underwear under her supersuit, she gets epic visible pantyline. Therefore she must go commando. This makes it extra unfortunate that her suit is so easily torn.
 * The bookends of every edition lampshade this by pointing out the "skintight" outfit does not show cameltoe, and some flashbacks show Emp's pantylines as a means to illustrate how long ago the scene occurred.
 * Her friend Ninjette does not appear to bother with (or have room for) panties beneath her bootyshorts either. She does not wear bras for that matter, but the latter is justified by her not having anything to put in them.
 * Gemini Storm: Not one of Elizabeth's outfits suggests she ever wears a bra.
 * In one of the early issues of The New Avengers, the team is captured and they are all stripped of the costumes. Spider-Man lets out that he doesn't wear underwear because it chafes him.

 * Seanbaby pointed out the same thing, albeit more crudely.

"Thor: I only wish Hercules himself had worn e'en a thong. 'Twas not a view I relished."
 * According to Thor, The Incredible Hercules has a distinct lack of underwear under his skirt.

Fan Works

 * Given how often Tsuruya wears Kimono in Kyon: Big Damn Hero, this trope is in effect a lot more than is immediately apparent.
 * Link in Legend of Zelda the Abridged Series and it's purely a comfort thing.
 * In a Axis Powers Hetalia doujinshii, Japan dolls up England in a yukata for a "date" with America. America soon lampshades the trope as they walk off together, and then one thing leads to another...
 * In Harry Potter and the Cracked Reservoir, after Harry starts dating Ginny, each of her brothers plays a prank on him as part of initiation into the family. One of the pranks was enchanting all of his underwear to freeze whenever he thought of his girlfriend.

However, at the end of the film, she's left with nothing but the white dress since those two aforementioned dresses were implied to have been destroyed by Frollo prior to her supposed execution so that she can be executed properly.
 * At the very beginning of the song "Honor To Us All" from Mulan, if you look very closely when Mulan is forced to take her green dress of and is pushed into a washtub (although in silhouette because she is stripped behind a canvas due to Mulan being a kids' movie), you can easily tell that she isn't wearing anything underneath.

Live-Action TV

 * Joey on Friends; it's mentioned a few times.
 * Notably while wearing "Chandler's pants"—not just a pair of Chandler's pants, but all of Chandler's pants. But prior to the pants-wearing, it's invoked by name to explain why Joey can't wear a rental tux after Chandler hid all the clothing Joey owned but wasn't wearing.

"Gunther: Hey buddy, this is a family place. Put the mouse back in the house."

Music

 * Meg White seems to like drumming without a bra. We don't mind, either.

 * Well, parents can chafe sometimes...

Theater

 * The song "I'm Not Wearing Any Underwear Today" from Avenue Q.

Video Games

 * In Destroy All Humans! mind-reading rednecks of both genders can reveal they are going commando. The same thing applies to senior military personnel much later in the game, even General Armquist.
 * The limited-edition figurine of Mushihime-sama protagonist Reco lacks panties under its skirt. Presumably because in the figurine, Reco is sitting on a stump, and you'd have to go out of your way to detach her from the stump.
 * Evoked in Persona 3, in a quite funny form. Cute kid Ken asks the main character if girls were Going Commando in the New year festival, and then he also asks what Going Commando means (he overhead it from Junpei, who also comments this)
 * If you play through the female protagonist's story in the portable version, Ken asks "aren't you girls cold?" with equally hilarious results.
 * Aigis tecnically is always going commando.
 * Note that this is because the girls are all wearing kimonos at the festival and there's a sort of urban legend that women who wear kimonos don't wear underwear.

 * Male example: A common joke about two Nintendo heroes, whereas Link and Marth are claimed to be Badasses because they enter the battlefield without their pants on. The images in the earlier games did make them look that way...

"Bart: Ahhh! Free and easy, Lis'! There's nothing like an unfurnished basement for pure comfort."
 * In one Metalocalypse episode, Murderface is introduced to the concept of "freeballing it". Nathan and Skwisgaar reveal they rarely wear underwear.
 * Well, Skwisgaar. Nathan estimates that he only wears underwear 65% of the time, which isn't really "rarely".
 * On the opposite end of the spectrum, the boy in The Snowman changes out of his pajamas directly into his clothes without even a pair of Long Johns underneath. Most likely done for humorous effect.
 * In The Venture Brothers episode "Ice Station -- Impossible!", Rusty confesses that he is not wearing underwear.

 * One episode of Total Drama World Tour entitled "The Am-AH-Zon Race" reveals that Cody is under the impression that nobody wears underwear in the Amazon and, therefore, he decides to go without. Gwen, upon finding this out through the use of X-Ray glasses, is quite disturbed...


 * In one episode of Quack Pack ("Koi Story"), Daisy is revealed not to be wearing any unmentionables under her mini skirt, when an earthquake causes her to bounce and lose balance before getting into spread eagle position in front of the viewers. When Gil presses a button on a remote that causes a large, rocky wall to split and reveal a giant fishbowl.
 * Chicago, from Producing Parker, often goes commando.

Real Life

 * Truth in Television, of course.
 * According to his autobiography Ain't Got Time to Bleed, Jesse Ventura was afraid that someone who was in his Vietnam War era SEAL unit would show up to shout "skivvie check!" at his swearing in as the governor of Minnesota. When he was serving, when that call was made others were obligated to stand up and drop their pants, to show they were sans underwear.
 * It's sometimes necessary for soldiers, because not having the chance to dry off downstairs can give you the mother of all jock itch.
 * Britney Spears was caught more than once going like this by the press.

 * Some women do this while wearing pants to avoid VPL (Visible Panty Line).
 * Liv Tyler while playing Arwen often had to go commando in order to wear some of the elvish costumes.

 * Taiwanese superstar, Jay Chou cheerfully admits to this. This fact is famous in Asian showbiz.
