Women

STEP 1.

Measure your body

Wrap the measuring tape quite tight around the fullest part of your chest.
Waist:
Measure around the slimmest part or your natural waistline, keeping the measuring tape level and parallel to the floor.
Hips:
Measure the fullest part of your hips, keeping the measuring tape level and parallel to the floor.

STEP 2.

Compare your measurements to the relevant size chart.

Compare your body measurements to the size chart to find your size. If your measurements fall between two sizes and you want a looser fit - order the larger size. If you want to go for a tighter fit, it is recommended to order the smaller size.

Important note:

If you want to order outerwear (coats, jackets) and your measurements fall between two sizes, we recommend choosing the larger size.
