jamas for me.
I usually wear underwear in bed too - like you say, sometimes sleeping naked can feel uncomfortable.
sleeping naked? but what if there's a fire in the middle of the night or you're confronted by a burglar... TOTALLY unprepared!
Stark bollock naked for me everytime. Even in the middle of winter.
I have only had half a sheet over me during the hot weather.
If I have flu, I might wear a dressing gown to sweat it out me.
Even if I am really hot I have to at least have a sheet over me. I can't sleep otherwise.
