How to take your measurements? You need a tape measure with centimeters, as centimeters are more accurate than inches.
Waist in centimeters (a):Measure around your natural waist. This is the narrowest part of your torso, usually near the belly button.
Enter Your Waist (60 - 118)
Hips in centimeters (b):Put your legs together and measure around the widest part of your hips.
Enter Your Hips (80 - 138)
