fit tips
if one of your measurements is on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.
consider your height first when finding your size, then your body measurements.
if your measurements for hip and waist correspond to two different suggested sizes, order the one indicated by your hip measurement.
