Wow! I can not believe how many of you sleep nekkid, lol, I can't imagine doing that. I usually sleep in pj pants (I have so many my mom prohibits me from ever buying another pair!) and one of my millions of t-shirts. The tshirt has to be short sleeved though and I HAVE to have a bra on to sleep. I've always slept with my bra on ever since I started wearing one. People tell me it's bad for you, blah blah, maybe so but I can't sleep if I'm not wearing one!
