How to find out what size you are
Start with the product you want to buy, then measure the body areas that matter most. Use waist, hips and inseam for jeans and trousers, bust or chest for tops and jackets, and foot length for shoes.
Which measurements matter most
The best measurements depend on the item. You can start with one measurement, but adding more relevant measurements usually makes the size estimate more useful.
Why clothing sizes vary by brand
Brands use different fit models, fabrics and cuts, so the same size label can fit differently across stores.
