How do cup sizes increase?
The cup size increases as you move from top to bottom on the chart. Bra sizes that share a row are called sister sizes, meaning they share the same cup volume (though they have different cup letters).

The bust size is the literal number you just read on the tape measure while contorting yourself into the “L” shape. The cup size, however, is the difference between your band size and your bust size. If your bust size is less than 1 inch bigger than your band size, you’re a cup size AA.

The rule of thumb is as follows: If you go up in the band, go down in the cup and vice versa. For example, a 32C could possibly fit a 30D or a 34B. If you’re a 34C, you might find bras that fit better in a 36B or a 32D. Knowing your sister size is useful to accommodate for size differences between brands.
