reading the comments after this article from Buzzfeed via Yahoo, that there are so many different reasons on both sides of this debate:
Personally, it varies for me, depending on a number of things. I sleep in the nude plenty of times. But sometimes I’ll sleep in a pair of undies and a tank top. Other times, I’ll sleep in a fleece top, and fleece socks but no undies. I never sleep in a nightgown. They get too twisty. Pjs and nightgowns are mostly loungewear for me, not sleepwear.
How do you sleep?
