Waist

Measure around your natural waistline — the narrowest part of your torso, usually just above your belly button.

Hips

Measure around the fullest part of your hips and seat, keeping the tape horizontal.

Height

Stand straight against a wall without shoes. Mark the top of your head and measure from the floor to the mark.
