Sizing Guidelines

FIRST, MEASURE FOR YOUR UNDERBAND SIZE

While braless or wearing a non-padded bra, measure around the underband, directly under your bust. The measuring tape should be level, measure in inches and be very snug. If this number is even, this is your underband size. If the number is odd, add one inch to this number, and then this is your underband size. (So if you measured 32 inches, you underband size is 32. If you measured 33 inches, your underband size is 34.)

NOW, THE CUP SIZE

Wrap the measuring tape somewhat loosely around the fullest part of your bust (at nipple level) and round to the nearest whole number.

Subtract your underband size away from your bust measurement and the difference between these measurements will reveal your cup size. Refer to chart below. For example, if your bust measurement is 36 inches and underband size (as calculated in the last step) is 32 inches, then the difference it 4 inches. Your bra size would be 32D.

Still not sure?

We've made things even easier for you by including a size calculator on all our sports bra product pages. Input your measurements in the tables and we'll let you know your recommended sizes across all style as you search.

Our bra sizes run true to size. So no need to go up or down a size from your normal day-to-day bra size. However, we like to remind everyone that you can be different sizes in different shops, like with normal clothes. So it's still important to double-check you get a good fit with the size you purcase.
