How do You Measure for a Bra Size?

To measure for a bra size, first use a measuring tape directly beneath your bust, keeping it as straight as possible. Round to the nearest number. If the result is even, add four inches. If the result is odd, add five inches. This is your band size. While wearing a bra that is not padded measure the fullest part of your bust. Round this number to the nearest number. This is the cup size number. Now, subtract the band size from the cup size. The difference in number of inches determines the cup size. The cup size goes up by one for each inch of difference.
