Bra Size Guide
Our size charts and measuring tips will help you order the correct bra size. We recommend starting with a soft measuring tape and wearing your best-fitting non-padded bra.
Measuring your Band Size: Stand in front of a large mirror wearing your best-fitting non-padded bra. Wrap a soft measuring tape around the bottom band, right under your bust. The measuring tape should be parallel to the ground and lay gently on top of your body without being too snug or loose.
Hint: Round your measurement to the nearest whole number. Ex. 29.5 should be rounded up to 30. Match your measurement to the chart above to determine your band size.
Measuring your Cup Size: Wearing the same bra, keep the tape around your back at band level, measure at the fullest part of your bust. Make sure the tape isn't too tight by taking a full breath in and exhaling so the tape falls to its most comfortable-yet-fitted position.
Hint: If the measurement falls on the half inch, round up to the nearest whole number.
Once you've got your band and cup measurements, simply subtract your band size from your cup size. Take the difference between the numbers and match it to the chart above to determine your cup size. For example we are going to use a woman with a 34" band size and a 37" cup size. 37-34 = 3. According to the chart above, our woman would be a 34 C.
Additional tips to ensure the best fit:
Straps: Ensure your straps lay comfortably on top of your shoulders. If your straps dig in to your shoulders you probably need to go down a band size. If your straps are constantly slipping off of your shoulders, your band is probably too small. If you have sloped shoulders, try a racerback bra or a style with convertible straps. Remember, 90% of support should come from the band not the straps.
Cup Coverage: Your cups should lie comfortably and smoothly against your breasts. If you don't fill out the cups or there is wrinkling and gaping, you need a smaller cup size. If your cups are overflowing or dig into your breasts, you need to go up in cup size.
Underwire: Underwire should lie flat against your skin and encircle your breasts. If your underwire is poking you in the arm or digging into your breast tissue, you may be wearing a cup size that's too small or the wrong style for your breasts. Keep in mind that breast placement and shape can affect how bras with underwire fit.
Band: Your bra band should rest firmly and comfortably against your back. If it digs in painfully, try loosening it. If it's already on the last hook, you probably need to go up a size. If the band is riding up your back, try tightening it. If the band still fits loosely, the size you're wearing is too big. Bra bands tend to stretch over time with wear. Your bra should fit firmly on the last hook when new.
