1. Chest
Wearing a bra, pass the tape measure straight across your back, under your arms and over the fullest point of your chest.
2. 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.
3. Hips
Pass the tape measure across your hipbone, around the fullest point of your hips.
