Most of the time I do, clothes are so annoying when you're a human hot water bottle lol but during winter I often put an oversized shirt or something on
I used to sleep naked but right now I am a care taker for my disabled father so that kind of kills that. I sleep in shorts right now. I miss being nude all the time.
Here in Finland it can get kinda cold at nights so its MUST have to sleep either naked or with panteis on ;3 theres nothing better then wrapping your self in a warm blanket and get all cozy x3
