Sister Sizing

Every bra size has ‘sister sizes’: a family of alternate sizes that share cup volume, but have different band circumfrences.

How does it work? When band sizes go up, cup size goes down — and vice versa. So, if you’re a 36C, you might also like the fit of a 38B or 34D, depending on your preference.
