BAND SIZE: Standing straight up with an unpadded bra on, measure closely around the chest just under your arms, right above the bust. If your result is a fraction, round to the nearest whole number. (ex. 33.7" rounded to the nearest whole number, your band size is 34")
BUST SIZE: While wearing an unpadded bra, loosely measure around the fullest part of your bust. Round to the nearest whole number. (ex. 34.5” rounded up to the nearest whole number, your bust size is 35”)
CUP SIZE: Subtract your final Band Size from your final Bust Size to find your Cup Size. (1” difference = A Cup, 2” B Cup, 3” C Cup, 4” D Cup, 5” DD Cup)

Fit:Ultra-tight, second skin fit.
Digging, bouncing, pain, and permanent damage—fighting with your sports bra shouldn’t be part of your fitness routine. So we spoke with athletes. We worked with Dr. Joanna Scurr, the authority on biomechanics of the female body. And we tested hundreds of prototypes. The result is the revolutionary Armour Bra™, sized so both band and cup fit your exact body type. Now, instead of squeezing into a Small or falling out of a Large, you can choose your exact size for the perfect performance fit.
