It depends on the girl. Some do not because they feel suffocated. Mostly girls do not wear, because even during the day wearing a bra hurts and the breast might swell. It gives comfort, release, openness and freshness to a girl to get out of the bra and breathe normally.

Girls usually just wear whatever size they are. If they wear smaller bras, it generally has something to do with them having a smaller body.
Sometimes girls don't wear bras because their boobs hurt or they are just having a lazy day.. LoL

We don't HAVE to wear bras. Some women don't. It just depends on the women. Some wear bras because they like it. Some aren't comfortable so they don't.
