How to measure your size

Use a cloth measuring tape to measure your body. All measurements should be taken while standing up straight with feet shoulder width apart. Take measurements over the type of undergarment you would wear under the clothing.

1 CHEST/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 HIPS

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