How to Measure

Chest - Measure around your upper body, under your armpits and over the fullest part of your chest and shoulder blades.
Waist - Bend to one side to find the natural crease of your waistline.
Inseam - Measure a pair of pants that fit you well. Measure along the inside of the leg from the crotch to the hem.
