I was looking at this topic and was trying to think of the maker of my first bras.
I had initially worn hand me down bras from my sister for my first few years of bra wearing. It was after my 16th birthday I had my second "bra talk" with my mother. I had to start wearing full-time because of my development.
As many of you know, she took me bra shopping for my own bras at our local JCPENNEY. They used to carry Adonna bras. I remember how much I liked them. They were the first time that I wore an underwire. They were a 34C. In comparison, my mother wore a 36B. That being said, I can see why she felt it was important that started wearing a bra full time. It used to be quite the exception that I wore a bra. Now, living as a woman , it's kinda the rule.
