I'm 25, and I was a late bloomer. I was an A cup until I got to college at 19, where I grew to a B cup. I feel as if I'm a "B and a half", even though that's not a real bra size lol. and still to this day, I am growing. I started off at 5'7" at 15-16, and I recently grew to be 5'9" (I was 5'8" from age 19 up until this year). Why are some people late bloomers, and how will I know when I'll be done changing and growing if I'm still experiencing these things still at 25? Thanks!
