How to measure:

hip and waist measurement guide

For most of our styles, the hip measurement is the most important to consider for selecting the best fit, especially if you're between sizes.

waist - Measure the smallest area of the torso - right above the belly button and below the ribcage.

hip - Measure the widest part of the hip
