We suggest you follow these procedures for determining your correct size before ordering.
HOW TO TAKE ACCURATE MEASUREMENTS:
Standing with your feet together, measure your bust, waist, and hips as instructed below. If possible, have a friend measure you. BE SURE NOT TO WEAR ANY PADDED OR RESTRICTIVE UNDERGARMENTS. Ensure that the tape measure is parallel to the ground, not twisted, and held snug against the body. Avoid wrapping the tape measure too tight as this will provide a false measurement. If you are between sizes, use your best judgment based on if you want your garment to fit more or less snug.
BUST: Measure under your arms and around the fullest part of your bust. THIS IS NOT THE SAME AS YOUR BRA SIZE!
WAIST: Measure around the smallest part of your waistline. This is usually about two inches above your navel.
HIPS: Measure around the fullest part of your hips.
