My grandmother (and mother) used to (and still does) tell me and my sisters that if you sleep in your bra, your boobs won't grow. So we were always sure to take off our bra's before bed. Ironically enough, she (my grandmother) dosen't wear underwear to bed, does that mean that her butt grows at night?
