How to measure:
CHEST:
With your arms relaxed at your sides, have someone measure under your arms and over the fullest part of your chest.
WAIST:
Bend to one side. The crease that appears is your natural waist. Without pulling tape too tight, measure around waistline.
INSEAM:
Take a pair of pants that fit you well and lay them flat. Measure from the inside crotch seam to the bottom hem.
ACCESSORIES - HATS / BELTS:
For belts, measure over waistband of pants. For hats, measure your head at the point where your hat would fit comfortably.
