How to Measure
Underbust Measurement
Measure around your ribcage, directly under your bust. Keep the tape measure snug but not tight, and ensure it's parallel to the floor.
Bust Measurement
Measure around the fullest part of your bust, ensuring the tape is straight all the way around and parallel to the floor. Wear a non-padded bra for most accurate results.

Sports Bra Fit Tips
Band Fit: The band should be snug but comfortable, providing most of the support. It should not ride up in the back.
Cup Fit: Your bust should be fully encapsulated with no spillage. The center gore should lie flat against your chest.
