Measure up following the tips below. You can get a friend to help or do it yourself in front of a mirror. Then refer to our size guides.
Take your measurement around the fullest part of your bust making sure the tape measure is not too snug.
Your natural waist lies below your ribs and above your hips. Its the smallest part of your waist. Make sure you breathe deep and relax your tummy when you’re taking your measurement.
Measure the widest part of your hips. Usually not at your hip bones but a few centimeters lower and where your booty is at its fullest.
