The bra size contains at least one letter and only one number. Like 34 A. The size of the band of the brassiere which is the size of the rib cage is numerically measured. e.g., 30, 32, and 34… The cup size is measured alphabetically. It refers to the size of the breasts compared to the rib cage. In other words, how much bigger the breasts are than the rib cage. e.g., A, B, C... Double letters, such as AA and DD means there's 1" difference between band and chest measurement. AA is smaller than A of one inch. The same goes for the B versus BB and C versus CC. It isn't until you arrive at DD that the double letters mean one inch more. So DD is an inch bigger than D. There are no international standards for bra sizing that is why it's all a bit confusing!
