Bra Size Unavailable? Sister Cup Size To The Rescue!

Even after finding your correct bra size, there are times you might need help from ‘Sister Cup Sizes’. Wondering what sister cup size means? These are alternate sizes where the cup volume stays the same even though the band size and cup letter change. The reason being that cup sizes aren’t consistent by letter, they’re consistent by band size. Larger the band size, larger the cup. Therefore, the cup of 34B is same as 32C or 36A.

Here’s a bra sister size chart to help you slip into the perfect one!
