Rangiku Matsumoto has her rather large boobs practically spilling out and occasionally makes strange references to them, but only resident pervs Kon and Keigo react to them. Her captain, Hitsugaya, seems to be the one least bothered by it. Supporting character Hisagi has a crush on her, but he usually doesn't show it outside of a few omakes and a couple of key filler episodes. Folks in the Soul Society, all being Really 700 Years Old, are probably just used to Rangiku at this point. That and it's completely intentional; one Shinigami Encyclopedia moment had her teaching the other female lieutenants and court seats the "proper way" to expose their cleavage. While totally non-canon, it was also totally in-character. This is spoofed in the "next episode preview" for the Beach Episode. Rangiku's pissed that nobody complimented her on her bathing suit, to the point that she's getting ready to strip just to get some attention.
Harribel's number was marked on her right breast, and when she revealed it to Hitsugaya the young captain was more interested in her number than her womanly bits. He's just a kid after all. A kid who works with and is eye-to-bosom-level with Matsumoto. Harribel's release makes her into an epic Ms. Fanservice, with little more than pasties covering her nipples, and a very tiny miniskirt. No-one in the series proper comments on it, and the only mention of it by any character is Ichimaru Gin in one of the Arrancar Encyclopedia segments, who states he'd never be able to wear such a skimpy outfit.
While in a healing hot spring, Ichigo is shocked to discover Renji, Byakuya, and Rukia are all completely submerged despite being comatose. His reaction completely overlooks the fact that Rukia is floating with her butt completely exposed. Kirinji lampshades it, by wondering why Ichigo's not commenting on the "perfect peach".
In an episode of Code Geass R2 a group of girls from an Ashford Club dress scantily to have Lelouch Distracted by the Sexy. It doesn't work because it's actually Sayoko posing as him. Made hilarious by the fact that Sayoko actually says "Those bodies have no effect on me!", making the girls suspicious and causing Lelouch to tell her "Please don't have me say things like that."
A number of characters in Digimon: Rosemon, Lillymon and Angewomon immediately come to mind. There were some random passerbys noticing LadyDevimon's appearance in one episode of 02, calling her a "sexy-looking woman".
Divergence Eve seems to take place in a future where huge breasts are (apparently) so commonplace that men have stopped caring.
Lucy has an undertone of The Tease, and wears comparatively demure clothing, though she goes more for 'cute' then 'sexy'.
In one episode when Grey was in Lucy's body, he kept trying to remove his shirt and the men would have hearts in their eyes and shout "Yeah!"
However, no-one seems to care about Cana walking around with just a bra on her top half, nor Erza's frequent use of Chainmail Bikinis. Nor any other similar outfits.
On the male side, nobody ever says a word about Natsu's vest with nothing underneath. Grey's stripping habit is usually also only brought up as a quirk, and no females seem affected. But then we have this reaction to Natsu vs Gajeel:
In Full Metal Panic!, towards the beginning in the first arc, Kaname is naked minus a ripped patients uniform and her underwear for a good portion, but none of this is focused on or even pointed out by any of the characters, including Kurtz, a borderline super pervert, due to the seriousness of the situation and the various military fighters coming after the group.
The Major's default outfit in the first season of Ghost in the Shell: Stand Alone Complex rarely attracts any attention. However, in one episode she gets thrown into some garbage during a fight and has to change her costume into something even more Stripperific than usual. When Chief Aramaki sees her, he asks her if she's trying to get his attention.
GUN×SWORD: Like The Major, people tend to notice Carmen 99's getup a lot less then you'd think is normal. During the Beach Episode, the only one with any real modesty issues is Wendy.
Given that Hayate the Combat Butler's Hayate is a Chaste Hero, you'd think they'd play this trope straight. Twice Hinagiku has distracted him though (which she seems to appreciate), and he seems to notice his co-worker Maria every once-in-a-while. When the buxom Athena talks to him though, she has to make sure he notices her. He seems completely unfazed upon encountering his master while she's bare, but he disguises this by saying that he's not interested in her, despite her being only three years younger than him. Several times, he is somewhat distracted, but still recovers himself before the girl in question even gets over the shock of being seen. He's not clueless about sex appeal, just not affected by it like normal guys. Pointed out when Miki shoves a magazine in his face, and states that he's the perfect one to take Hinagiku out because of his reaction.
InuYasha: When Sesshoumaru saves an almost-dead Kagura from drowning, she's naked to the waist. Although she (just barely) protects her modesty with a carefully placed arm their conversation remains focused on how to kill Naraku. Sesshoumaru never reacts to her state of dress and is more focused on warning her that she's going to get herself killed if she continues like this and only visibly displaying his worry once she's out of sight. The anime plays this trope even straighter by cutting out Sesshoumaru's worry over her but also subverts this trope with Jaken who yells at her to cover up, something he never does in the manga (in the manga, he plays this trope straight by ignoring her state of dress). Note that in the manga, Sesshomaru had his back turned to Kagura the whole time and was not looking at her.
In Naruto Shippuden, Naruto tries to use his Sexy Jutsu to convince Killer Bee to train him in how to control his tailed beast. Up to this point, the Sexy Jutsu had men fall to their knees before Naruto. Bee's reaction? Slamming the door in Naruto's face (he preferred mature women).
In Onegai Twins, Miina and Karen think that Maiku might be gay because he isn't distracted by all the fanserivce. Hilarity Ensues given the fact that he's straight but is on a tight deadline and is trying his hardest not to let himself get distracted.
In Ookiku Furikabutte, none of the characters (not even the perverted ones) on protagonist's team seems to notice that their coach's boobs are bigger then her head. Hilariously, the catcher for one of the opposing teams they face sees her to be a "big distraction" that makes him "feel funny" but has no idea why (while the camera zooms in on her chest).
In Sailor Moon, the Sailor Senshi are always seen wearing super-mini skirts, even revealing panties every now and then — even while fighting Princess Snow Kaguya and her Snow Dancers in a freezing winter storm in the Sailor Moon S Movie — but no-one seems to particularly care for their inappropriate outfits.
Yoko from Tengen Toppa Gurren Lagann; although Simon and Kamina are indeed distracted at first, they get used to it. This becomes something of a Running Gag, as even towards the series' end there are still one or two characters who are utterly distracted by Yoko, especially during one episode where it seems she changed outfits midscene causing one of the minor characters to quietly flip out. One of the few cases where an unqualified inversion of the trope with a female being distracted by males could have been pulled off, and Yoko doesn't even blink at a perpetually shirtless man in impossibly Cool Shades.
Vandread: Most of the Dread pilots are shown wearing jumpsuits identical to Meia's (which is skintight, but covers everything), but Barnette and Jura get away with much more Stripperiffic outfits, which no one ever seems to notice. Justified because the three guys on the ship were raised in a woman-free environment and told that women were evil monsters. It takes most of the series before any of the main guys actually admit they each like a particular woman.
One Piece: Boa Hancock was somewhat disturbed by the fact Luffy was this, separating him from nearly all the men she had known her entire life, and even tried to have him killed for it (among other reasons), but eventually she got over it and even fell in love with him. Other notable examples include Trafalgar Law and Smoker.
Luffy takes this to such an extreme that he has the world's most beautiful woman in front of him. Completely naked. And he is dissapointed that there was no food.
Chopper (as an anthropomorphic reindeer) isn't attracted to human females, meaning he's the only male character who can see Nami naked with impunity.
Don't Forget Mihawk, the guy is so serious he wouldn't care if hancock was standing next to him naked.
Despite Revy's borderline Stripperiffic outfit in Black Lagoon (justified only on grounds of the climate), Rock doesn't seem to even notice how little clothes she's wearing. Likewise, she doesn't really seem to care how much Rock sees.
A Certain Magical Index: Accelerator. At one point he walked in on Yomikawa, Yoshikawa, and Last Order showering, and his only comment was that he was irritated that they'd forgotten to lock the door.
Yuugen Kaisha: Mamoru is not the least bit distracted by Ayaka's habit of sleeping in the nude, or by the way she shows up for breakfast each morning - in nothing but her underwear with her top open. This may be because he's Just a Kid and therefore isn't effected by her, well... EVERYTHING
This tends to come up as Fridge Logic for older readers in a lot of superhero comics for children for the simple reason that sexuality just isn't addressed at all in a lot of them. For just one example, one comic had She-Hulk losing a fight with the villainous Wrecking Crew, which consists entirely of very-heterosexual big muscular super-powered thugs; who, to make matters worse, had just broken out of prison. She Hulk (whether or not anyone has a fetish for her green skin) is a very attractive woman, dressed in a skimpy skin-tight superhero suit, and at the mercy of a bunch of sex-starved thugs in the middle of a vacant lot; in short, were reality to ensue, she could fully expect to be gang-raped. Since this all takes place in a comic book for children, however, the Wrecking Crew just gives her a severe beating and then goes its merry way.
Andrew complains that he's bored while the Slayers are playing strip poker, and is completely nonchalant when he sees Buffy and Satsu naked in bed together.
That's because he's really, really gay.
Supergirl, before the '90s. She flies and wears a skirt. Thankfully, as of the late '00s, she also wears sensible biker shorts under it.
Power Girl is the superhero exception. The inability of men to ignore her obvious assets has even been used as a plot point in the occasional story. Her reactions to this vary. For the most part, she only takes offense when people are being obvious perverts about it and/or assume she's just a Brainless Beauty.
The Sandman: Her outfits aren't exactly Stripperiffic so much as looking like she forgot something when she got dressed, but Delirium more often than not walks around wearing ripped-up mesh shirts and/or open tops that expose her nipples, and nobody ever comments on this. Mind you, the nipples are pretty much the only thing there to see, because Delirium is a child. And it's probably notthefirst thing you notice about her, anyways. But still, it isn't even mentioned once. It's hard to tell how old she's supposed to be physically, apart from "definitely not an adult". The general fandom consensus seems to be 13 or 14 (which is still kinda young for Distracted by the Sexy, granted), but it seems to fluctuate depending on the artist (justified by her being an Anthropomorphic Personification).
Occurs in Sin City quite a bit. Marv's parole officer is a hot lesbian who first shows up in-story, wearing a pair of panties and nothing else. Marv doesn't seem to care. In another story, Wallace spurs the advances of Blue Eyes, a deadly assassin who seduces men to their deaths. While he isn't aware that she's an assassin at first, he still does not succumb to taking advantage of her when she throws herself at him.
In an issue of Action Comics, Cat Grant all but thrusts her newly augmented chest at Clark Kent, and he doesn't even glance downwards.
Films — Animation
Aladdin. Princess Jasmine's skimpy top and gauzy harem pants barely get a mention by the other characters, and this in a part of the world where such attire would be deemed thoroughly inappropriate for a member of nobility or royalty. (The custom of veiling in the Middle East originated among noblewomen in the Byzantine Empire, as a way of distinguishing themselves from more revealingly attired, lower-class harem girls and prostitutes. The more respectable a woman is, the more she wears.) Granted, she wears a concealing hood when out on the streets of Agrabah, but often goes without it when traveling to other places.
In Tangled, charming rogue Flynn Rider tries to use his good looks, in the form of chat-up lines and his devastating "smoulder" look, to try and seduce Rapunzel into doing what he wants. Unfortunately, Rapunzel has lived isolated from the world in a tower all of her life, has no experience with or understanding of seduction techniques, and consequently has no clue what he's doing — and is appropriately unimpressed. This causes Flynn no small amount of frustration.
Flynn:(mid-"smoulder") This is kind of an off-day for me, this doesn't normally happen.
Flynn: (After being hit with a frying pan) "You broke my smoulder."
Tracy Ryan is wearing only a pair of panties and an unbuttoned dress shirt when she's casually talking to Sebastien Guy in the kitchen in Girl for Girl.
An argument occurs between the main characters, a doctor and his wife, in Eyes Wide Shut. The wife (Nicole Kidman) accuses the doctor (Tom Cruise) of being aroused by seeing naked female patients. He assures her that he thinks nothing of it.
The scene in True Romance in which Clarence confronts Alabama's ex-pimp, Drexl has a pretty nifty example. Drexl informs Clarence he has taken no notice of the pair o' titties on the tv screen next to him, to which Clarence responds with a neat retort that among other things explains both yes he has noticed, and no he does not care.
In the 2004 remake of Alfie this trope is used to demonstrate that a relationship is in major trouble.
NakedGun 33 and 1/3: Tanya's attempts to distract a guard with sexy antics while her boyfriend slips a bomb into one of the Academy Award envelopes. None of her erotic gestures seem to work. It is only when she starts popping bubble wrap that the guard responds... by shooing her away and popping it himself.
In Fanboys, Windows is so into talking to his online girlfriend that he doesn't even notice Zoe flashing him,
Parodied, among other things, in Airplane II: The Sequel. While in a mental hospital, Stryker is making a painting of flowers, the model of which is shortly revealed to be next to a nude model. Stryker just thanks her as she covers up and walks off.
The coed shower scene in Starship Troopers. Neither the men nor women in the shower ogle each other.
In Indiana Jones and the Temple of Doom, Indiana Jones enters Willie's room and begins intently serching for a secret passage. Willie, meanwhile, believes that Indy showed up to have sex with her, and she repeatedly offers herself to him while he ignores her.
Salmissra: You interest me, ugly one, I've never coupled with an ape before. Beldin: Forget it, I like my women fat and hot-blooded. You're too cold for me, Salmissra.
The Lensman universe takes it one step further, with entire planets of essentially human beings in which complete nakedness is the norm, and others in which the inhabitants wear only the minimum of garb. In fact E. E. “Doc” Smith was fond of this trope, and the Osnomians and like peoples in the Skylark Series also wore very little (then again, they had telepathy machines and tended to execute perverts).
One of the survivors in World War Z tells a story about watching a stag film at his friend's bachelor party post-war. The lead actress is having sex on the hood of a BMW Z4, but the survivor can only think about what a shame it was that no one builds cars like that anymore.
In the Gaunt's Ghosts novel First and Only, Rawne and some unsavoury character discuss contraband at a seedy bar, paying no attention whatsoever to the showgirl doing a striptease on stage.
Parodied in a sketch of The Benny Hill Show, where Sue Upton went to the beach in a conservative blouse and below-the-knee skirt, sat on a beach chair, and was immediately surrounded by guys trying to look down her blouse and up her skirt. She changed into a skimpy bikini and all the guys went away.
In The Sopranos, a lot of the time is spent in a strip club, but little if any is spent watching the show there.
In Arrested Development, Lindsey goes to prison to visit her father George, then gets offended when none of the other inmates hit on her. She keeps visiting in increasingly slutty clothes, hoping for some catcalls, but the men act like they don't notice her, frustrating her immensely. Eventually, George begs her to stop, revealing that he's been bribing the guys to act respectful and her attention-seeking behavior has nearly exhausted his savings.
At least Once an Episode on Project Runway the models strip down and try on their clothes in front of several people and cameras. Almost nobody has ever commented on their bodies unless it's to discuss their measurements' effect on the clothes.
In the Babylon 5 episode "Lines of Communication", John Sheridan barges into Susan Ivanova's quarters in the middle of the night babbling about his latest brainstorm — while Ivanova is wearing nothing but a very slinky nightgown. Sheridan completely fails to notice until it's pointed out, which offends Ivanova a bit. This is par for the course for the two of them, however.
Liquid Snake runs around shirtless outside in Alaska. Sniper Wolf runs around in Alaska wearing Absolute Cleavage. The most shamelessly egregious example of this, though, is with Meryl, during her ending. She (dressed in a tiny black halter top) tells Snake that he (shirtless at the time) can't go outside dressed like that, or he'll freeze, and runs off to find something warm to put on herself. He puts on a shirt, and she puts on an orange jacket which has no sleeves, leaving her arms totally bare. The game attempts to Hand Wave it by saying that everyone on the project is using "anti-freezing peptides", but Snake, injected with the same peptide, is the only character in the entire cast to respond to the cold even vaguely like a normal person.
All female soldiers in the Command & Conquer: Red Alert series. Just look at the RA 3 trailer: what kind of military uniforms have cleavage like that?
Persona 3 lampshades this a little. There are various armors one can get during the game that change a character's appearance. Theyare... Yeah. Try handing one of these off and Yukari will bitch you out while Mitsuru is simply shocked, but doesn't say anything audible. They'll still wear them, mind. And since this is an ATLUS game, being Distracted by the Sexy can land you a game over real quick.
Arcanum: Of Steamworks & Magick Obscura also averts the trope. The game lets you walk around in your underwear, but everybody civilised refuses to talk to you. However, the even more revealing Barbarian Armor is socially acceptable. Although the shopkeepers comment and charge you MORE.
Special mention goes to FF6's Celes. She spends 95% of the game wearing a Leotard of Power with a cape, and nobody ever blinks an eye. When she tries her hand at being an Opera singer and wears a Pimped-Out Dress, Locke blushes at seeing her. However her artwork has her dressed in much more modest gold coloured clothing.
Terra's Morph/Trance: The guys in the game swoon when she winks at them, but none of them have a problem with Terra transforming into her Esper side, casually shedding all her clothes and fighting the enemies nude. The Barbie Doll Anatomy helps.
Sigma Star Saga has every female Krill wearing what amounts to an alien bikini, yet no one seems to bat an eye. Well, Recker does a couple of times early on, but that stops after the first chapter.
City of Heroes allows the player to build a character who is dressed in the next best thing to total nudity, if that's what you're into. None of the contacts or villains will react to it or even notice.
Gloria from Devil May Cry 4. She's dressed like an even more Stripperiffic version of Lady Gaga, she's "qualified" to wear that outfit, she's an agent of a freaking religious cult and the only character who addresses her outfit is Dante... who laughs his head off. Granted, Gloria is really Trish, but still, man.
Nero's reaction to her... clothing, is to look away in slight irritation.
Nobody in the Halo universe acknowledges that Cortana is naked. Even in the first game where her figure was very noticeable. To make it even weirder, in Halo Wars, the A.I. Serina is wearing a fairly conservative set of clothing. Guess the more skin a translucent computer girl shows, the more processing power.
Word of God even said that she chose her appearance partly to throw off people and give her an edge in conversation. Which makes it even weirder. The Barbie Doll Anatomy might have something to do with it.
In Pokémon, some Pokémon can have an ability called "Oblivious" which prevents them from being affected by the infatuation status caused by the move Attract. Prior to Pokémon Black and White, the Red Flute item can also negate the effects of Attract, in case a Pokémon has been Distracted by the Sexy.
For a more direct example, Skyla, a Gym Leader in Black and White, wears a Stripperiffic outfit and has the biggest rack in the game, yet gets almost no attention whatsoever for her appearance. In fact, nearly every male NPC who talks about infatuation at all will refer to Elesa, another Gym Leader. Any compliments directed at Skyla are for her excellent piloting skills (which she genuinely has, as demonstrated in Pokémon Black 2 and White 2, and is NOT an Unusual Euphemism).
You can run around in next to nothing in Fallout 3 and none of the NPCs will comment on it. While Dukov will flirt with female player characters even if they walk in wearing so much power armor that you cannot tell the gender of the person inside.
In a volcano stage in Tales of Hearts, female characters consider disrobing because of the heat. In two cases, this flusters the male characters, but when the young Beryl offers, she's greeted by uncomfortable silence. Also of note: Kunzite refuses to participate in these conversations.
In the first Diablo, the succubi were so sexy they actually caused some controversy; their bosoms and rear ends are clearly visible, and they aren't wearing anything except arm warmers and thigh-high boots. The player characters don't seem to notice. The players, on the other hand, that's another story.
Phoenix Wright: Ace Attorney — Trials and Tribulations has Dahlia Hawthorne, who leaves every male character she meets lovestruck... except for Miles Edgeworth and Diego Armando.
This is basically an Edgeworth superpower. Back in the first game, April May flaunts for all it's worth. The Judge is charmed, Phoenix is irritated... and Edgeworth never changes expression.
Every time Mia Fey appears. Then again, people barely seem to find it worthy of mention that a ghost is in the courtroom, let alone one that's bursting out of her someone else's top. In fact, the only person who even comments on it when she's alive is Gumshoe, and even then only briefly.
Shion and Mion. Despite having large racks (not to mention being identical twins), no-one ever seems to notice except in Higurashi no Naku Koro Ni Rei's Pool Episode, and there is exactly one scene of either of them Gainaxing.
The Boobs of Steel article on this very wiki is a detailed, scientific discussion of whether or not cup size is actually proportional to strength, and why. The writer at least was definitely Not Distracted By The Sexy.
Justice League. This trope is generally played straight with almost all of the superheroines, though there are exceptions, such as Green Arrow's interest in Black Canary.
One minor exception involves a conversation between the Flash and the Elongated Man in the episode "The Ties that Bind". As the scantily clad Fire walks past them during the conversation, Elongated Man very clearly twists his head and stares as she walks past.
Wonder Woman once walks past a dress store and notices a skimpy bikini and she asks the Flash who would wear something that demeaning.
Lampshaded in an episode involving criticism of the Justice League as role-models, a talk show host remarks, "And what about this Wonder Woman? I've seen showgirls that dress with more modesty than she does!" It annoys her to no end.
Wonder Woman: And what's wrong with the way I dress?! Flash:(to Green Lantern) You wanna take that one?
South Park episode "Raisins" had Cartman and Stan as the only boys who weren't stunned by the girls at the Hooters-like restaurant, Cartman because he was focusing on the food and Stan because he was dealing with a break-up. Stan's case is also worth pointing out because the other boys took him to the restaurant specifically to distract him.
Stripperella. Although it seems to swing between this and Distracted by the Sexy regularly, as convenient to the story. Played straight in just about every scene except when she's performing on stage as her civilian persona (at which point people are supposed to be distracted, or she's not doing her job properly). The majority of the villains she fights are all too well-aware of how dangerous she is, and fights accordingly.
Sym-Bionic Titan has Kimmy try to seduce Octus into doing her math test by going into a sexy dance routine (with much booty-shaking and a bit of pole-dancing... presumably the censors were sleeping during this scene). Octus' response? Not even blinking at her routine, and an irritated "No!" when she's done. Though they do end up dating by the end of the episode.
One B-plot of an episode of The Simpsons involved Homer winning a professional boudoir photography shoot, which took place in the Simpson's basement. When he shows Marge the "Homererotic" result, she gets excited over the pillows and curtains the photographer used in the background, then drags a protesting Homer off to go shopping so she can start redecorating.
Homer: (whining) But I was gonna score!
Marge: No you weren't.
In the "Jurassic Bark" episode of Futurama, Amy and Leela are doing some gratuitous wrestling in skimpy gym outfits, but Fry is too preoccupied with the impending resurrection of Seymour to be bothered.
In the episode "The Six Million Dollar Mon", Fry is trying to eavesdrop on a conversation Hermes and Bender are having, refusing to help Leela and Amy rub on their new scented body oil in the shower.
Jungle Pam Hardy. We're surprised anybody ever got around to actually drag racing Jungle Jim.
Life-drawing classes. You're pretty much used to it after the first two sessions. Doesn't hurt that life drawing models aren't necessarily those you'd desire to see otherwise. Art models run the gamut of body types. Also, it's work. (Well, school, but it amounts to the same thing.) When you're forced to do something, that pretty much sucks all the enjoyment out of it no matter what it is.
Communal showers. They start out disturbing, and end up just being awkward or a non-problem.
People working in Theater or Dance get used to naked or nearly naked bodies as an everyday occurrence.
Small Dessous stores. Women walking around in their underwear, casually discussing the respective bra/ their boobs
Nudist beachs/clubs have this as a requirement. And it's pretty easy. (See "Life drawing classes" above.)
Male gynecologists (and pretty much doctors in general). Likely relates to the reasoning mentioned above for life-drawing classes, only more so. Doctors have to deal with a lot of Fan Disservice — very much a matter of "not distracted by the unsexy".
Like the aforementioned doctor-types, tattoo artists and piercers who deal in genital work get quickly acclimated to all sorts of things, or they don't have jobs for very long.
The origin story of the "Get Out" Frog meme. A goon was sharing a photoshot of a female porn star on Something Awful and everybody got far more interested in the frog plush in the corner than the woman (here◊ SFW).
A blogger claimed to see a topless woman walking the streets of New York in May of 2012 and "...what was even weirder? No one even flinched....Not one person turned to gawk at this woman's bare breasts."
I know I'm not going to get any, so why would I fall for that?
