Women's Fit Guide

Bra fit guide

There are two easy steps to finding the right size and fit.

Step 1: band size

Wrap a measuring tape closely around the rib cage, just below the breasts. This is the under bust size. If this measurement is 33 inches or less, add 5 inches. If this measurement is more than 33 inches, add 3 inches. If this calculation results in an odd number, round up to the next even number. This is the band size.

Example: 29" under bust size + 5" = 34" band size

Step 2: cup size

Loosely measure around the fullest part of the bust. Subtract the band size from this number and compare the results to the chart below. This is the cup size.

If the difference is:

1" = A cup size

2" = B cup size

3" = C cup size

4" = D cup size

5" = DD cup size

6" = DDD cup size

Example: 36" bust measurement - 34" band size = 2" or B cup size

Foundations / Daywear

Cross graded cup sizes refer to fitting. Example: A customer who wears 34a may also fit 32b by adjusting band and shoulder straps.

Loungewear and Sleepwear

Perfectly Fit Bra
Please note that Calvin Klein Perfectly Fit bras offer average cup depth and coverage as compared to traditional department store brands. We recommend that customers take this into consideration when making purchases.

Petite Fit
The petite fit is designed to provide a more accommodating fit for the petite or smaller than average woman. These bras have a reduced cup size and band size. The straps and apex points are positioned closer together for a smaller fit. Select styles have thicker foam pads for added lift.
**Please note when purchasing a petite bra, you may wear a slightly larger size if you do not normally wear the petite fit.
