Racerback Sport Bra

At BYATHLETE we understand how crucial the right size and fit are to feeling and looking wonderful. We've worked closely with our athletes and analyzed client feedback to create precisely sized items to fit anybody. To determine your size, use the chart below.

HOW TO MEASURE

Bust: Measure around the fullest part of your chest. Keep the measuring tape horizontal.

Waist: Measure your natural waist circumference, which is the area just above your hips.

Hips: The broadest region of your hips, or around the middle of your glutes, should be measured while standing with your feet together.

Center back sleeve: With the arm relaxed, take a straight measurement from the center of the back neck to the shoulder point and from the shoulder point to the wrist.

Inseam: Standing with straight legs, measure from the top of the inside thigh to the bottom of the ankle.

Between sizes?
We advise selecting the following size up if your measurements fall between those shown in our sizing chart.
