Ditto for a character from Nagasarete Airantou. Having lived on an island her entire life without ever having met a male, everything she's learned about inter-gender relationships was from note pornographic books and magazines that washed up on shore.
"But it says in this magazine that you don't wear anything under the apron when serving dinner..." "Don't listen to that kind of magazine!"
In one chapter of the manga, a mirror image of girl-type Ranma come-to-life tries to seduce the original Ranma wearing this outfit. Nabiki hangs a lampshade on the trope and its popularity in Japan at this occasion.
Ukyō, one of Ranma's suitors, wears it at the beginning of the second Ranma ½Non-Serial Movie (subtitled Nihao My Concubine in the U.S.). Partly justified in that she is a cook by profession, she was cooking at the time, and she was wearing a bikini-bottom underneath — they were at the beach.
In Sakura Diaries, Urara uses this outfit several times as a method to try to seduce her cousin Touma, with little success.
In chapter 53 of The Wallflower manga, Sunako, of all people, does this when suffering from a strange delusion: she was so humiliated that she ended up buck naked on top of Kyohei (due to a cursed gem that made her act like an exhibitionist — long story) that she forcibly blocked it out of her mind. Unfortunately as a side effect, when she bathes the next day, she blocks out the fact that she's naked afterwards, and hallucinates that she's instead already dressed. Seconds later, she's wandering around the house in Hadaka Apron, making breakfast for the guys. The four Bishōnen who share the house with her can't believe it, either, and Kyohei has to chase her around school keeping her safe — in her mind, she's already wearing her school uniform under the apron, in reality, she just flashed her roommates and was a few minutes away from streaking the entire school.
One episode has Lala wearing this when preparing to make a meal for Rito. When Rito tells her she's supposed to wear the apron over clothes, she adds a bikini bottom. She also does in a recent chapter of the manga, saying her friends told her boys like it.
And again in one of the OVAs, where Rito actually takes an interest. And for the manga, Rito accidently forces her into one a second time when he takes over Peke.
In the manga, when Lovable Sex Maniac Fukuyama is giving cooking lessons, he does one of his trademark Instant Cosplay Surprise to put Kirie, Koyomi and Miharu in aprons, though he let them keep their underwear (at first). When Lethal Chef Kirie proves still resistant to his teaching, he strips her nude save for the apron, under the pretext she needs her full freedom of movement. This ends up as a Congruent Memory situation: Kirie learns to cook properly, but can do so only when otherwise naked. (Her Home Economics teacher is not amused.)
Siesta, the Meido from Zero no Tsukaima, uses this in one episode to attract main character Saito. Works really well.
Chi of Chobits is sort of naive about this and sort of not—she picked up the behavior from one of Hideki's hentai manga, but she doesn't understand anything about it other than that Hideki liked the manga.
Samataro's goddess mom in Kamisama Kazoku wears it at her husband's request. But then, when her son and his female angel guide Tenko come home to see her in it, she doesn't mind at all. She even proudly explains that "It's called being naked under the apron. It's a romantic gesture that really tickles mortal men's hearts."
Yoshinoya-sensei, the Cosplay Otaku Girl of Hidamari Sketch, also does this once after seeing that another class was engaged in baking. To be fair, the aprons those girls are wearing ARE rather cute. And she reassures her students that she is wearing a swimsuit underneath — it just doesn't show when viewed from the front.
The eponymous Ai of Video Girl Ai does this fairly early on in the series. After an untouched first printing, the Japanese publisher declared it scandalous and made Masakazu Katsura draw panties on her for all subsequent print runs. Because that makes it better.
Lilika does this in Burn Up! Scramble. For some reason, she takes off the underwear that was all she was wearing before. She then realizes Maya is out of salt and goes out to get some. Lilika should definitely be kept away from alcohol.
Great Teacher Onizuka: When Fuyutsuki puts him up to help him cram for his exams, Onizuka fantasizes about having her wear nothing but an apron.

In Highschool of the Dead, Saeko Busujima wears this and panties when she has to do the cooking for the group while her clothes are drying from being cleaned for the first time since the Zombie Apocalypse started. Even funnier in a bonus chapter in the manga when Takashi's friends say that they want to see Saeko in just an apron. Even more egregious when the plot conspires to have Saeko make a Big Damn Heroes entrance riding on top of a Humvee, still in just the apron and panties, and proceeds to do battle with a zombie horde wielding a wooden sword. It's that kind of series.
In one episode of Oruchuban Ebichu, while Ebichu is cleaning house, Ebichu gets an anonymous call from a creeper asking what they're wearing (not knowing that the caller is a talking hamster), and Ebichu replies innocently, "Well, all I'm wearing is an apron, but besides that, I'm naked..."

Goshuushou-sama Ninomiya-kun: The girls wear aprons and School Swimsuits (seen in the page's picture) in one episode while cooking dinner for Shungo's sister. Pity anyone who walks in on them because they get roped into wearing them as well. (It's implied that the mushrooms they were using in the stew were intoxicants or aphrodisiacs.)
Deconstructed along with a lot of other nudity tropes in Ano Natsu De Matteru: it's not intended as fanservice so much as an accurate depiction of what a nudist would wear while cooking.
In Is This a Zombie?, Yuki's friends suggest that she serve Ayumu food to get him to fall for her. Yuki imagines herself serving him food while wearing only an apron and freaks out. Her friends wonder where she got the apron idea from, they just said to serve him food.
This is a fetish for Kumagawa of Medaka Box, to the point that he eventually names his clique in the school the Naked Apron Alliance, and continuously makes wagers where one or more of the losing females will have to serve him in this state. When Kumagawa (a.k.a Naked Apron-senpai) won, nay, DOMINATED a popularity poll, to the point that he received more votes than 2nd, 3rd, and 4th place combined, beating even the main characters, he finally got his wish.
Io of the Amazons makes armor for Wonder Woman. She wears a leather blacksmith's apron but not a shirt (or bra) under it. She still wears pants so it's not a literal example of Naked Apron, but it's close.

Pauline Lafont in Chabrol's Poulet au vinaigre.

(He's covered up by a newspaper he's conveniently reading at arm's length while walking down the stairs.)
Joe: Helen, what is with that apron? I thought we agreed, all nude all the time! Helen: I am not cooking bacon naked.
Technically, it could be said that Chewbacca's wife wears one about 5 minutes into The Star Wars Holiday Special, but it's just confusing — like the rest of the show.
Played sadistically in the episode "Authority". The manager of a fast-food joint receives a phone call from a police officer, who tells him to bind, gag, and strip-search a female employee until police arrive, leaving only her apron on.

Equipping an apron but no other top on a female created character in Soul Calibur IV and Soul Calibur V results in their usual bikini top disappearing. Oddly, if the apron is broken, their bikini top reappears.
World of Warcraft has a similar look when equipping a tabard (and optionally a belt) with nothing underneath it. Notably, since tabards (unlike most armor) aren't damaged when you die, this is used to give some semblance of dignity to "corpse runs". However, since you do not lose your gear when you die, and anything you have in your bags is also damaged when you die, the practicality of this is somewhat suspect. It also makes you look NAKEDER, since the tabard looks accident prone, and covers your underwear.
Tyria from Ar Tonelico 3 wears one over a swimsuit in her true ending.
In SmackDown vs. Raw 2011 equipping an apron results in female's characters bikini top disappearing.

The statue of Vulcan on Red Mountain in Birmingham, Alabama, was built to symbolize the city's thriving steelmaking industry. From most viewpoints, Vulcan looks majestic with a big blacksmith's apron and a raised hand. However, for decades the neighborhoods behind Red Mountain enjoyed the sight of a giant iron butt on top of the mountain, since Vulcan is only wearing the apron and it doesn't wrap around. Recently, the statue was taken down, and repaired. The iron moon is still shining, but it's not aimed at a residential area now.
