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.
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.
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.
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.
- In Axis Powers Hetalia, an early running gag in the manga was that not only does Italy sleep in the buff, but he also has the occasional tendency to forget to put pants on when he wakes up.

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.
