Can you tell me the difference in bra cup sizes?

There are two parts to a bra's size: the chest size (also called the band size) and the cup size. The chest or band size is represented by a number (32, 34, 36, etc.) and is the part of the bra that runs across a girl's chest and around her back. The cups are the parts of the bra that hold the breasts and come in letter sizes (AA, A, B, C, etc.).

If the difference between your band size and cup size is less than 1 inch, your cup size is AA. If it's 1 inch, your cup size is A; 2 inches, you're a B; 3 inches you're a C, 4 inches you're a D, and so on.

To figure your size: Follow these simple instructions.

• Run a tape measure just under your breasts, all the way around your back and rib cage. The tape measure should rest flat on your skin and lie straight across your back - not so tight that it digs in, but not so loose that it sags down in back.
• Make a note of your measurement and add 5 inches. That's your chest size.
• To measure cup size, take the tape measure around your body across the fullest part of your breasts.
• Write down this number and subtract your chest measurement from it. The difference between the numbers is a way of figuring out your cup size.
