Fit tips
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.
How to measure
- BUST: measure around the fullest part of your bust, keeping the tape measure horizontal.
- WAIST: measure around the narrowest part (typically where your body bends side to side), keeping the tape horizontal.
- HIPS: measure around the fullest part of your hips, keeping the tape horizontal.
