How to measure
Hint: For the most accurate results, measure yourself in your underwear.
Chest: Measure around the fullest part of your chest, keeping tape firmly under your armpits and
around your shoulder blades.
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 trouser that fits you well. Measure along the inseam, from the crotch
to the hem.
Tip: If you are 5'4" or under, we recommend trying 7/8 as full length.
