How We Measure UpYour unique shape, size, and breast tissue density will influence your bra fitting experience. The measuring process is designed to guide you to a starting band size and cup size. From there, it's important to try on different styles to find the best fit for you.
- Visit a fitting professional or recruit someone else to measure you.
- Wear a natural-fitting lingerie bra that maintains your natural shape—with little to no padding or minimizing features.
- Breathe deep and stay relaxed.
Measure around your rib cage around the bottom band, just under the breast. The tape measure should feel quite snug. Round the measurement down to the closest inch.2. Band Size Conversion
Using our measurement guidelines below, find your corresponding band size based on your rib cage measurement.3. Bust Size Measurement
Measure the bust over the fullest point of the breast. For larger-breasted women, the fullest point may not be at center, and is often lower. As breast tissue can fluctuate as much as 20%, round up to the closest inch.4. Cup Size Conversion
Subtract your actual rib cage measurement (step 1) from your actual bust measurement (step 3). The difference in inches is your suggested cup size. If the difference is between sizes, round up to the larger size.

On the middle hook, ensure it's snug and lies even. If it rides up, it's too loose and/or the straps need adjustment. Chafing can occur if the band is too loose.the band is too loose.
Scoop your breasts into the cups, ensuring they are centered. The breast tissue should be fully contained, but the bra doesn't pucker or wrinkle. Anything that spills out the top or side indicates the cup size is too small.
If applicable, make sure it sits flat against the body. Any gaping indicates the need to go up a cup size.
They should not slip or dig. Adjustable straps can offer a more custom fit. If the support feels like it's coming from the straps, you may need a smaller band size.

Here are some common challenges and our suggested solutions.

Sports bras are a great solution for the extra sensitivity women may experience during pregnancy or nursing. Look for a style with front-adjustable straps that can adjust with your changing body. Plus, those front-adjustable straps can make it easier to breastfeed.WE SUGGEST:
Even with a well-fitted sports bra, some women experience straps that continuously slip off the shoulders. Keep straps in check a racerback or crossback style.WE SUGGEST:
