Choosing The Right Size
Body measurements are given in centimeters. If your body measurement is on the borderline between two sizes, order the lower size for a tighter fit or the higher size for a looser fit. 

1. Waist
   Measure around the narrowest part (typically the small of your back and where your body bends side to side), keeping the tape horizontal.
2. Hip
   Measure around the fullest part of your hips, keeping the tape horizontal.
