1. WAIST MEASUREMENT

Measure around the narrowest part of your natural waistline, keeping the tape comfortably loose without pulling tight.

2. HIP OPACITY POINT

Measure around the fullest point of your hips and glutes while standing with feet together to ensure maximum squat opacity.

3. INSEAM LENGTH

Measure from the bottom of the crotch seam down to the inside ankle bone for precise 7/8 or full-length placement.
