Chest: Wrap a cloth measuring tape under your arms across the fullest part of your chest.

Waist: Wrap a cloth measuring tape around your waistline just above your hips. The tape should be slightly loose not tight.

Help Tip: If the measurements for your chest and waist result in two different suggested sizes then order the size provided by your chest measurement.
