What do you wear when sleeping?

This is something I have been thinking about lately. In literally every clothing store for men I can find pyjamas... but I have never heard about or seen any adult man ever use pyjamas... I stopped using pyjamas at 10 and all my male friends stopped about that time too... my dad and grandfathers don't use pyjamas either.

On the other end of the spectrum however I feel like every single woman I have dated, been friends with etc... (my mom, sister) uses some kind of pyjamas or nightdress.

So the question is what do you wear when you sleep? And why?

Underwear only (boxers, briefs, panties)
Nightgown/nightdress
Naked
