Measurements on the sizing chart reflect the actual measurements of the body’s circumference (not product’s measurements). Use a cloth measuring tape to measure your body. All measurements should be taken while standing up straight with feet shoulder width apart. For maximum accuracy, take measurements next to skin.

Measure around the fullest part of your chest under your armpits with your arms relaxed at sides. Keep the measuring tape parallel to the ground.


Measure around the natural waist, which falls at the natural curve of the body--the indentation between the hips and the ribcage. The measuring tape should be close to the body but not snug.


Wrap measuring tape around the fullest part of the hips and buttocks. Keep the measuring tape parallel to the ground.
