Measurement Best Practices
Remove excess layers of clothing and measure comfortably snug to the body, using a cloth measuring tape. If you don’t have one, you can use a string and measure it against a yardstick or standard measuring tape. For best results have a friend help.
CHEST: Measure around the fullest part of your chest, under the armpits.
WAIST: Measure around the smallest part of your waist, near the belly button.
HIP: Measure around the fullest part of your lower body, typically around your butt or upper thighs.
INSEAM: Measure inside your leg starting at the crotch, down your leg to the floor.
SLEEVE: Start at the base of your neck, measure out to the back of your shoulder and down your arm to your wrist.
