Fit notes / 01
Size Guide
Measurements are in inches, with centimeters in parentheses. Garments are measured flat; if you are between sizes, size up for a relaxed fit.
Measure with care
How to measure
Measure the chest or bust at the fullest point, the waist at the natural waistline, and the hips at the fullest point. For shoes, stand with your heel against a wall and measure from the wall to the longest toe.
All measurements are approximate. For fit questions after an order, see the Returns FAQ.
