Bust: If possible, get a friend to help. With arms relaxed at your sides, measure the fullest part of your bust, keeping the tape parallel to the floor.

Waist: Measure around your waist, in your underwear, at the point where your trousers would normally ride. Keep one finger between the tape and your body.

Hips: Stand with your heels together, and measure round the fullest part of your hips, keeping the tape parallel to the floor.

Full Length: Measure from your shoulder bone to shoulder bone to the floor.
