Nope, boxers and a t-shirt for me, maybe pj bottoms in winter time / some socks if its like sub-30 out.
When I was a kid I wore pyjamis. Nowadays I tend to sleep in my boxers. In summer though I get hot and sweaty. Boxers become uncomfortable so I sleep naked. For those that think it doesnt feel right, just try it. Trust me, after a few weeks you'll probably prefer it. I did. At first it didnt feel right. I felt bare and empty. Now it just feels better.
