Oda (Arknights) - Topless but wears soft leggings that are suitable for lounging around in

Chief Meredith (Path to Nowhere) - Nothing but a dark purple dressing gown and fluffy black thermal socks

Big, BIG and comfortable t shirt

Very funnily enough, Saren prefers to wear a dragon onesie despite her age. It makes her feel a bit comfortable.

OC sleeps in gym shorts and a short sleeve shirt

pajamas! but if the place is too humid then just a shirt and shorts

boxers, anything else is way too hot

Naked probably tbh

The first answer that came to mind was some cotton pyjamas and a night cap LOL. But that's too dorky even for him.

But I think it depends on the situation, in winter he does probably sleep in some comfy pyjamas, while in the summer he just switches to boxer briefs and sleeps like that.

Though if it's one of those nights both him and Skadi don't bother getting dressed back up after the deed and just sleep naked in eachother's embrace

jacksy is usually too tired sleepy to care about what they wear but if they can keep themself awake long enough to change they get into a big oversized hoodie and crash on the bed waiting for exu to come and cuddle them

Mylinda wears a sort of silky satin purple chemise with lace. She likes to be as comfortable as possible when she rests

(nsfw text) depends. usually it's comfy cotton pyjamas, but if they fucked before then probably nothing. they'll shower before going to sleep if that's the case tho.

Most of them is just good ol' shorts and a t-shirt

Usually flannelettes cause they’re my favourite

Either a big shirt or nothing but socks

very bold of you to assume dr linni sleeps (when he is dragged to bed, he just sleeps in comfy underwear, a giant sweatshirt stolen off a certain cat, and blankets he burritos himself up in)
