How To Measure

  • Waist: Measure around your waist, slightly below your natural waist, where you normally wear your pants. Insert your forefinger between the tape and your body to allow ease in fit.

  • Hip: Measure around the fullest part of your hips, inserting your forefinger between the tape and your hip to allow ease in fit.

  • Inseam: Measure a similar pant that fits you well. Measure along the inseam, from the crotch seam to the bottom of the hem.

  • Tip: If you are 5'4" or under, we recommend trying 7/8's.
