STEP 1: MEASURE YOURSELF BUST Measure around the fullest part of the bust, keeping the tape horizontal. WAIST Measure around the narrowest part (typically the small of your back and where your body bends side to side), keeping the tape horizontal. HIPS Measure around the fullest part of your hips, keeping the tape horizontal. STEP 2: FIND YOUR SIZE Use the chart below to determine your size. If you're on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit. If your measurements for bust and waist correspond to two different suggested sizes, order the size indicated by your bust measurement.
