Place one end of the tape measure at the fullest part of your bust, wrap it around (under your armpits, around your shoulder blades, and back to the front) to get the measurement.

While in a relaxed position, measure around your natural waist - the narrowest part of your waistline.

Stand with your legs and feet together and measure around the fullest part of your bottom, approximately 20 cm or 8 inches below your waistline.
