How to Measure

1. Shoulder Width

Pass the tape measure straight across from the tip of one shoulder to the other, just above your shoulder blades.

2. Chest

Pass the tape measure across your back, under your arms, and over your breastbone at its widest point, keeping the tape measure horizontal. It should sit snugly against your body but should not be pulled too tight.

3. Waist

Pass the tape measure around your natural waistline at the narrowest point of your waist. The tape measure should sit snugly against your body but should not be pulled too tight.
