OK girls, I have read some things here about bra size....I think I understand what the 32/34/etc. means as that is a measurement around the chest right?...but what in the world is the A/B/C etc. mean.....sorry to be so stupid but i am :(

Yea the number is around the ribs and the letter is how much more it is to go around the ribs and the boobs.

I have wondered this too.

Bust size, the length around the chest on your boobs, highest point, and the length below the breast known as the Band size, substrate bust size with band size, and get the difference.... If the difference between the two numbers is less than an inch you are a AA cup, 1 inch is an A cup, 2 inches B cup, 3 inches C cup, 4 inches is D cup, 5 inches DD or E, and 6 inches F cup.

hope it helps....
