UK sizing is another system that frequently confuses international shoppers. UK clothing sizes run two numbers higher than US sizes — a UK 12 is a US 8 in women's clothing. Men's clothing is more straightforward with letter sizes matching between the two systems. UK shoe sizes are one number smaller than US sizes for men and two numbers smaller for women — a UK women's 6 is a US 8.
