How to measure your band and cup sizes

The more accurate the measurements of your cup and band sizes, the more accurate your bra size result will be. You can take these measurements yourself using a soft tape measure or you can ask a friend to help. Remember, there are also fitting specialists who offer their services at lingerie stores and can help you find an accurate bra size. Whoever takes your measurements, you will need to stand in an upright position and should not be wearing a loose top or bra. If you are taking the measurements yourself, it is best to do so in front of a mirror.

Cup: place the tape measure around your bust at its fullest point (make sure the tape measure is snug but not tight).

Band: place the tape measure around your body immediately under your bust (where the band of your bra sits).
