Why the US number is so much smaller
The US scale starts at 0 and counts up in steps of two. The European scale starts at 32. The gap stays at 32 numbers, which is why US 12 is EU 44.
The British number sits between the two: UK is US plus 4, so UK 16.

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
US 10 is EU 42, US 14 is EU 46. Both scales run in steps of two, so the gap of 32 numbers stays the same in every row.
