Nude. Not sure why you would need to put on any clothes - they don't serve any use, and whoever ends up in your bedroom is someone who's probably seen you naked already anyway.
Of course, when I'm sleeping over at friends, I usually just take off my pants and socks, so I end up sleeping in shirt + underpants.
i have slept nude or in a snug t-shirt my entire life. i detest clothing on myself while i am sleeping because it gets twisted up (specially bottoms) as i move through the night, so no thanks
