Actual garment measurements above refer to the width with garment lying flat.

Double the garment measurement for Chest/Waist/Bottom to find full circumference

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, taking care to keep 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.

4. Sleeve length

Keeping your arm straight by your side, measure from the tip of your shoulder to the base of your thumb.
