what is the band size on a bra

The band size on a bra is the measurement around your ribcage, where the bra underband sits, and is represented by a number (like 34 or 36). To determine your band size, you should measure snugly around your ribcage, directly under your breasts, and then add 3 inches to this measurement. If the result is an odd number, you should round up to the next band size. For example, if your ribcage measurement is 31 inches, your band size is 34. If it's 32 inches, your band size is 36
