At what age did you start wearing a bra/try on a bra for the first time?

I was about 11-12 years old.  I had very clear and pronounced breast development that could have used support.  I tried my older sister’s bra and it fit perfect.  And no, I didn’t know the cup size.

After developing breasts at age 13, I tried on one of my sister's bras out of curiosity if I actually did fit bra given all the continuous comments at school that I should wear one.

They were right, and I was amazed at how well I fit a bra and how good I looked wearing one. At that point I had to accept that I did have boobs just like the girls in my class. 

I also realized I was more comfortable physically and mentally wearing a bra.

While I started developing at 11/12 I don’t remember trying on my mom’s halter top until 13/14ish. By then I could pass the pencil test, so large B or small C? Can’t say for sure, but it was obvious at that time I could have used a real bra.
