Size Guide
Pick a category, find your usual size in the first column, then read across for the same size in other countries. Each table starts with body measurements so you can size from a tape measure. Where a product uses the brand's own scale, the label on that product page takes priority.
How to measure
Use a soft tape over light clothing. Keep it level and snug, not tight. Between sizes? Take the larger for outerwear, the smaller for close-fitting knits and swim.
| Measurement | How to take it |
|---|---|
| Chest / Bust | Around the fullest part of the chest, tape under the arms and across the shoulder blades |
| Waist | Around the natural waist, the narrowest point above the hip bones |
| Hips | Around the fullest part of the hips and seat, feet together |
| Inseam | From the top of the inner thigh to the ankle bone, standing straight |
| Foot length | Stand on paper, heel to a wall, mark the longest toe; measure heel to mark. Use the longer foot |
| Head | Around the head where a hat sits, about 1 cm (½ in) above the ears and eyebrows |
| Hand | Around the palm at the knuckles, excluding the thumb, dominant hand |
| Finger | Wrap paper around the finger, mark the overlap, measure in mm; or the inside diameter of a ring that fits |
Measure feet and fingers at the end of the day, when they are largest.
