BUST: Measure the bust line at the fullest part of your chest. Pull the tape as tight as you can without changing the shape of your breasts
WAIST: Measure the circumference of your waist. Use the tape to circle your waist (sort of like a belt would) at your natural waistline, which is located above your belly button and below your rib cage.
HIPS: Stand with both feet together and measure around the widest part of your bottom, at the top of your leg.
