When you get sweaty they suck, so bad cause they like stick and just, ew. But I like to wear them, cause if you didn't then your boobs would look weird and would bounce around all the time ahaha and there pretty :")

It depends on breast size and comfort. If you are small...go without. Some like pushing them up so they don't look like droopers.

Apparently not wearing a bra can reduce the risk of breast cancer, so I try to avoid wearing them whenever I can! :D

No, i have gone without a bra when ever i can!

Being a 34D/32DD I'm pretty much screwed in the summer either way. If I don't wear a bra the crease under my breasts gets sweaty and irritated. If i wear a bra the crease under my breasts gets sweaty and irritated, so it's a no win situation. And in the winter time because of my excema under my breasts gets dry and I develop rashes that I have to constantly use cream for to get rid of. Sure having larger breasts is fun sometimes, but not all the time. I'm just glad I don't have the really big ones that get so bad that women develop yeast infections under there.
