M in numbers and country sizes

| 36 | S | 8 | 4 | 38 | 42 |

M maps to exactly one European number, 38. Letter sizes are still a coarser grid than numbers, because every brand draws the boundaries a little differently.

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 S (European size 36), above it L (European size 40). If you land between two letters, the number sizes help: they are a finer grid.
