I enjoy sleeping naked and I enjoy cozy pjs. For that matter I also enjoy starting in pjs and ending up naked ;-p
I sleep naked as much as I can which can vary depending on the time of year especially as I’m a paraplegic or if I’m home alone. If I sleep in anything it’s usually just one of my husband old t shirts and socks but while I was pregnant I kinda had to wear underwear unfortunately unless things got out of hand cuddling before sleep
