HOW TO MEASURE
Measure around the fullest part of your Bust, wearing your bra, with your arms relaxed at your sides.
Measure around the narrowest part of your Waist at your naturalwaist. To find your natural waist, bend to one side. There will be a crease just below your rib cage: that's your natural waist. Don't worry if this seems higher than where you actually wear your pants.
Measure around your body at the broadest part of your Hips, keeping your thighs together. This should be where your legs meet your torso.
