I know this is an older thread but some of the stories are so funny.
When I was in school I was an early bloomer. I had a 36C chest when every one else was padding their training bras. Mom still had me in those thin little, no support things that looked pretty. Well, needless to say gjym class was horrible and I'd find ways to skip the class. Parents got called in and I finally confessed that it hurt to run around, all that bouncing...so Dad took me immediately to JC Penny to the adult bra section and annouced loudly, voice reverberating through the department "My baby girl needs a good bra so she don't bounce when she runs."
And years later every time we're at the store with a bra section, "C.C., You need any bras?" loudly, across the store. "No Dad, thanks. I'm 40 years old. I can buy my own now."
