Size Chart

To find your size, use a fabric measuring tape to measure the circumference around your rib cage right below your bust and around your bust at the widest point. 

The chart below is for our standard sizes XS-XL. If you find that you are at the upper or lower ends of the measurement range, you may want to consider our extended sizes which allow you to mix band and chest sizes. For more info on that, click here.

RIB CAGE BUST
XS 29 - 31 27 - 31
S 31 - 33 30 - 36
M 33 - 35 35 - 41
L 35 - 37 40 - 46
XL 37 - 39 45 - 49

 

Lume Six Sports Bra Size Chart

 

Our wear-testers have found our sports bras to be true to size. If you like the fit of another sports bra you have that uses alpha sizing (small, medium, large, etc), we recommend ordering that size.

Sizing is subjective and preferences vary depending on the intended activity and personal preference. If you are unsure of your size, we offer free shipping + free returns so you can order multiple and return what you don't want to help make sure you find the right size.
