Chest

With arms at sides, place tape measure under your arms and run it around the fullest part of the bustline and across the shoulder blades.

Waist

Find the natural crease of your waist by bending to one side. Run tape measure around your natural waistline, keeping one finger between the tape and your body for a comfortable fit.

Hips

With feet together, run tape measure around the fullest part of your hips/seat, about 7 to 8 inches below your waistline.
