Same. If I don't wear a bra, they jiggle every time I walk and when I'm on my period, it hurts like crazy cause they're all tender. -.- And wearing a bra to sleep doesn't cause back problems, but NOT wearing a bra can cause more saggy-ness when you get older... I think I'll wear the bra.

I was a D when I was fourteen. XD Then I went to a C for a while, then I gained weight again and have remained at a D cup ever since.

I don't think they're changing bra sizes. O.o Creeeppy... It probably depends on the brand - like with clothes and shoe sizes.
