some girls tell me they do...I think that is the most uncomfortable thing in the world. I have a DDD cup..so maybe if I were smaller it wouldn't be..hmmmm Derk thats funny! lol Holy Answers!! thanks guys!! :D when i first got my bra (11yrs old) my mom told me it would stunt my growth to wear it to bed... I wondered if it was like saying "eat your carrots and you can see in the dark" I usually don't wear anything under my pj's unless I am at a buddies house or something.... Chris? you're really a doctor? lmao...
