Sizing Calculator

Enter your measurements into the fields below:

  • Wear your current best-fitting underwire bra (non-padded, non-minimizing) and take the measurements indicated in the picture.
  • Your bust measurement is taken with the tape parallel to the floor, snug but not pulled tight enough to deform the breast tissue, around the fullest part of your bust.
  • Your band measurement is taken with the tape parallel to the floor snugly beneath your breasts. This should be in the crease where your breasts meet your body - you may need to lift your breasts to position the tape correctly.
  • Please round measurements up to the nearest 1/4 inch - do not add. For example, if your measurement is between 34.5 and 34.75, use 34.75. If your measurement is 34.5, just use 34.5.

If this size is significantly different from your typical US bra size, please email your measurements and the size and style of the bra you measured in to for sizing advice.

If you are accustomed to wearing a much looser band than your measured or calculated band size, you may prefer the sister sized bra in the next band size up (go down a cup size). For more information on fitting, visit our Fit Tips page.
