How to Measure
- Chest
Measure just under arms and across shoulder blades holding the tape firm and level. If your chest falls between sizes, order the next size up.
- Natural Waist
Bend side to side and find the natural bend in your body; this is your natural waist. Note: It may not be the smallest point.
- Hips
Measure the fullest point between your natural waist and crotch.
