I like sweatshirts and fun pajama pants. If its hot I like spaghetti strap tops and fun pajama pants. If it was a night where I knew something might happen with my boyfriend I might wear some sort of sexy silk nightie. Nothing trashy or raunchy but something with a "come hither" appeal.
I wear shirts that are way too big or a tank top and loose pajama pants, usually ones that I stole from my older brother. But it depends on the weather; if it's extremely hot I want something loose but during winter I'm more likely to wear something tighter. Personally I wear LESS during winter because I like the feel of the warm blankets. Kinda strange how that works.
I don't really like wearing anything when I go to sleep apart from when my periods are up or if a friend is over . If I'm cold then I'll put on a big top but I like to keep my clothes to a minimal when I'm trying to sleep .
