BUST Use a tape measure to measure around the fullest part of your bust. For a more accurate measurement, please wear an unlined / unpadded bra when measuring. UNDER BUST Measure directly under your bust and straight around your back. WAIST Your waist is the narrowest part of your torso. Wrap your tape measure around this area, which is usually on or close to your navel. Make sure the tape is snug but not digging into your skin. HIP Find the widest part of your hips. Generally, it’s 8 inches below your waist. TORSO Measure from the highest point of the shoulder, beneath the crotch and back up to the starting point.
