I have had no problems with Nicki's hair. When it gets a little flat I just put it in curlers for an hour and it bounces right back. As for the bodysuit, it is a blouse/underwear in one. Its the sort of thing that doesn't require separate underwear because it *is* underwear. I have worn many in real life and they have always had a lined crotch (like nylons) that mean they are meant to be worn sans panties. However I do dislike the skirt, I feel it is too short and has this odd tendency to ride up on her torso.
