Waist: To find your natural waistline, bend to one side to find the natural indentation in your torso. This is your natural waist. Run tape around natural waistline, keeping the tape parallel with the floor.

Hip: Stand on a level surface with feet together. Measure around widest part of hips and bottom, keeping the tape parallel with the floor.
