Size Guide

How to measure
Chest: Measure around the fullest part of your chest
Waist: Measure around the narrowest part of your waist
Hips: Measure around the fullest part of your hips
Fitting tip
If you're in between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit. If your measurements for chest/bust and waist correspond to two different suggested sizes, order the size indicated by your chest/bust measurement.
Please note: all measurements below are body measurements and not garment measurements. Some items may appear tighter/looser due to different fits.
