Find Your Best Fitting Bra

Wrap a tape measure snugly around your body and below your bust. After breathing out, take your measurement. If it’s an even number that is your band size, but if it’s an odd number, round up to the closest even number.

Find Your Best Fitting Bra

Wrap the tape measure around your chest at the fullest part of your break. Subtract your band measurement from this number. If the different is 1”, then you are an A cup; 2”, then you are a B cup; and so on, through DDD.

Find Your Best Fitting Bra

Combine your band measurement and your cup measurement to determine your correct size.
