Question: what is the difference between uk and us dress sizes?
Answer: The size difference is 3 sizes between UK and US for women's and the UK is the smaller of the two. ... If you need a US women's size 9, this would be a UK women's size 6. This is exactly the same for half sizes, so if you're a 6.5 in the UK, it's simply a 3.5 in UK.
