they probably have curlers in their hair too. that would look pretty tacky. could at least slip into some clothes. hardly ever see this but who knows they are probably out there.again they would tacky but they really do not bother me.as long as they are not with me. UPDATE I see people in pajama bottoms a lot. guess this is some new fad.and it is not teenagers only. I see different ages doing this.and seem perfectly happy. oh well, to each their own. I cannot bring myself to wear pj, bottoms out in public. have them at home and they are comfy.
