How to measure before choosing a size

Use a soft tape measure and keep it level, snug, and not compressed against the body.
Measure over light clothing or underwear for apparel; bulky layers can add a full size.
For international conversions, treat the chart as a starting point and check the brand chart before buying.
If one measurement lands between two sizes, choose by garment: prioritize bust/chest for tops, waist and hips for bottoms, and the largest measurement for fitted dresses.

FAQ

Are UK and US clothing sizes the same?

Women's UK and US clothing sizes are not the same. A women's UK size is often four numbers higher than the US equivalent. Men's chest-based sizes may be closer.

What is a UK 12 in US women's sizing?

A UK 12 is commonly close to a US 8 and EU 40 in women's clothing.

Are UK shoe sizes the same as US shoe sizes?

No. Shoe conversions depend on men, women, kids, and the brand, so use a shoe-specific chart when possible.
