WOMEN'S APPAREL

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.

1 BUST

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.

2 WAIST

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.

3 HIP

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

Pro fit, fitted, semi-fitted, and loose fit
