For AWWA Briefs, the hip measurement is the most important measurement for selecting the best fit, especially if you’re between sizes.
Waist - Measure the smallest area of the torso which is above your belly button and below your ribcage.
Hip - Measure the widest part of the hip
With our larger sizing, every brand fit is different. For the best product fit experience with AWWA, rather than relying on numerical sizing, we highly recommend measuring your Hips to check our sizing for your body. 
Our AWWA Bralette fit is more inline with a sports crop with the most important measurement being the underband. If you are fuller busted than the optimal recommended fit, you can try sizing up one size.
To ensure the leak proof technology does its job our underwear fits slight more snug in the gusset than your regular underwear.
