Thread a tape measure under your arms, across shoulder blades at back and around the fullest part of your bust. Relax your arms at either side and keep the measuring tape parallel to the floor.Waist measurement
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 tape parallel with the floor.Hip measurement
Stand on a level surface with feet together. Measure around the widest part of hips and bottom, keeping tape parallel with the floor. Do not measure around your hip bones, this is too high. Measure around the widest part of your lower hips and bottom, often this is the upper thigh area.
Compare these measurements with the size chart below. If you are between two measurements, choose the larger size.
