MEASURE YOUR RIB CAGE:

Measure around your rib cage just under your bust. Round down to the closest inch. This is your rib cage measurement, which you’ll need to figure out your band and cup size.

FIGURE OUT YOUR BAND SIZE:

Take your rib cage measurement from step 1 and read across the chart below to find your band size.

SIZE BUST
XS 28-31" 71-79 cm
S 30-33" 76-84 cm
M 34-36" 86-91 cm
L 37-39" 94-99 cm
XL 40-42" 102-107 cm
2XL 42-44" 107-112 cm
1X 44-47" 112-119 cm
2X 47-50" 119-127 cm
3X 51-54" 130-137 cm

FIGURE OUT YOUR CUP SIZE - THIS IS A 2-STEP PROCESS:

First, measure around the fullest part of your bust. Keep the tape straight across your back. Round up to the nearest whole number. This is your bust measurement.

Now, subtract your rib cage measurement (step 1) from your bust measurement (step 3). The difference in inches is your suggested cup size. If you’re between sizes, round up.

BUST SIZE MINUS RIB CAGE SIZE YOUR CUP SIZE
3" 7.6 cm AA
4" 10.2 cm A
5" 12.7 cm B
6" 15.2 cm C
7" 17.8 cm D
8" 20.3 cm DD
9" 22.9 cm E

FIT GUIDELINES:

Every bra serves a different purpose for different activities and we recommend referencing each specific bra product description to determine the best bra for your body and sport. Our bras should generally fit snug. Wearing the bras too loose will not likely provide adequate support.

***Please note, a majority of our sports bras are medium support and medium coverage. If you are looking for the highest impact support that we offer; check out the X-Factor, Intensity or Moxie Sports Bra!

MEASURING TIPS:

We have determined that your waist measurement will most likely dictate your size. Right on the edge between two sizes? You can utilize your thigh and hip measurements as secondary guidelines to help you find the perfect size.

WAIST MEASUREMENT:

Measure around the smallest part of your torso, keeping the measuring tape as horizontal as possible.

THIGH MEASUREMENT:

Measure around widest area of the thigh.

HIP MEASUREMENT:

Measure around the largest area of your hips, encapsulating the roundest part of your gluteus.

Review Summary
Customers say this sports bra is comfortable and cute, with many praising its soft fabric and flattering open-back design. The strappy back appeals to those who want to show off their workout style.
