How to Measure
To find your best fit, use a soft measuring tape and measure directly against your body while wearing a light sports bra.
Bust
Measure around the fullest part of your bust, keeping the tape level across your back. Make sure the tape is snug but not tight.
Underbust / Bottom Hem
Measure around your ribcage directly under your bust where the sports bra band will sit. This determines how supportive the band will feel.
Length
Measured from the top of the shoulder strap down to the bottom hem of the bra. This measurement determines how much coverage the bra provides.
