How to measure yourself
Measure in your underwear with a soft tape. Three measurements are enough:
- Bust: around the fullest part, with the tape level across your back.
- Waist: around the narrowest part, usually a hand width above your navel.
- Hips: around the fullest part of your seat.
Keep the tape snug but not tight. The values in the chart are guide values, not a promise. If you fall between two sizes, go by your bust for tops and by your hips for trousers and skirts.
The sizes either side
Below it sits XXL (European size 46), above it 4XL (European size 52). If you land between two letters, the number sizes help: they are a finer grid.
