As the Maiden Forms
In the sunset of my pre-pubescence, when those famous fleshy protuberances began to sprout, I couldn't wait to get my first brassiere. It was called "Littlest Angel", by Maidenform. It had no cups, just a nylon stretchy fabric for the nascent buds.
But when these aforementioned buds began to get serious I graduated to a bra exactly like the one pictured above, in AA size, called "The Pirouette". When I got to A I knew I was really in luck. Adolescence is something.
