While pajamas or underwear are the most commonly depicted garments worn for sleep, it's also not uncommon to depict a person wearing nothing to bed at all. While this is Truth in Television, media often treat this as shocking or exotic, with the character who does it being portrayed as an oddball for doing so, and they're often comically opinionated about the superiority of their sleeping habit if questioned, often mentioning health or comfort benefits. In Real Life, somewhere around 25% of all adults sleep this way normally.
Sometimes used to illustrate the setting, such as a depiction of a period before sleepwear became mainstream, or character, as in showing a person prefers not to wear clothes at home at all or has other traits to them that make sleepwear either unnecessary or in some way a hindrance. Sometimes the characters simply don't have any clothes to spare, and sleeping without clothes is a sign of a dire situation or even poverty, similar to a Bankruptcy Barrel. And sometimes they sleep nude because they live in a very warm environment and would find extra insulation (in the form of pajamas) to be unnecessary.
Naturally, it also serves as a form of Fanservice, with the notion that nude sleepers are tied to seductive or sex-positive characters, with The Tease oversharing that she does it just to titillate others. Fan Disservice is also just as likely, with the common stereotype that old, ugly, or gross people also enjoy sleeping naked. As such nude sleepers are commonly either portrayed as very attractive or very repulsive.
A lot of awkwardness may happen if a character sleeps this way have to share a bed but There Is Only One Bed. A Shameless Fanservice Girl or someone with No Sense of Personal Space may not mind, but the other person surely will. Expect a Bedmate Reveal if someone who sleeps naked sneaks into another character's bed, intentionally or accidentally, with one of them usually freaking out and jumping to conclusions. A Modesty Bedsheet (or a woman lying on her front) can be employed if censorship is necessary.
When someone is woken up abruptly while in this state, it can also be an example of Naked People Are Funny or an Inconvenient Summons. Can sometimes lead to Dining in the Buff if someone chooses to get a Midnight Snack or make breakfast without getting dressed, or a Full-Frontal Assault if attacked in their sleep. May involve Clingy Sleepers, especially the nude sleeper.

- In an ad campaign for the Coco Chanel perfume "Chanel No. 5", Marilyn Monroe claimed that she only wore the perfume to bed, obviously to take advantage of the titillating factor associated with sleeping naked.

Aoi: I sleep in a way I don't like others to see. Especially men.
Riruri: Like wearing Chanel No. 5 or 6?
Aoi: Non. It's an original.

The second was after Miaka wakes up after her Bungled Suicide by drowning, which leaves Hptohori flustered.

For bonus points, she's sharing the bed with a teenage boy, and offers to take his virginity when he asks her if one can still have sex as a full body-replacement Cyborg (he turns her down). It's strongly implied that she mostly only bothers with clothes for social or practical reasons: as her cyborg body began life as a common civilian model from several years ago, there are probably thousands of women with her exact external body.
- Puru Two in Mobile Suit Gundam ZZ was nude in a suspended animation chamber upon her first appearance. Oddly, she didn't seem to mind at all when she woke up.

Not that he minds, though everyone else does. This gag has been largely abandoned (though Italy's sleeping habits remain the same). The anime edited things so that Italy sleeps in his underwear, which kind of missed the point of the joke, though this tendency of his was still referenced once in the dub.
