Nowt as well, unless camping in winter,

I sleep naked all the time. Even in the dead of what passes for winter in Louisiana.

My birthday suit & flannel sheets in the winter (Chicagoland)

Ok, I'll maybe not very sexy and old fashioned, I sleep summer and winter just in pyjama's. On warm summernights I tried to sleep just in boxer or nothing, but I wake up in the morning with a huge backpain. I live in a farmbuilding, that is not central heated, so in wintertime electric blankets are used too...
It feels so good, to get into a preheated bed in wintertime...

Panties and a t-shirt

The magical rationality that arises naturally from the internet.

Naked, except sox on my feet.

I sleep completely naked. Started doing it in college, and wow its awesome. Occasionally when I'm sleeping somewhere else I'll sleep in my boxers and it sucks.

Nothing

Would love to cover you
