We were all just talking about comfy undies, so I thought I would ask how you are most comfortable sleeping .... you know, what in: pjs, long or short nightgowns, tee shirts and sweats, in your birthday suit!!!! LOL Cotton, flannel, silky materials? Do you sleep with undies on, or without? We used to have these polls (discussions) at our lunch table where I used to work. It was always a kick to see how everyone is so different!! OK - here's my answer: I like to sleep in long silky nightgowns, because I toss and turn all night and it is sooooo much easier to turn over in bed in silky material (pjs or nightgowns, but I prefer long nightgowns). Also, I don't like the elastic of underwear on at night, so I sleep without the undies on!! You could say that I sleep in the nude--under my nightgown!! LOL Since all the kids are gone, and we don't have to worry about small kiddies crawling in bed with us, I don't have that worry about sleeping properly clothed!!
