Precision unit conversion
Clothing size numbers don't mean the same thing in different countries — a UK size 12 is not a US size 12, which catches a lot of people out when ordering from American or European retailers.
As a general pattern, US women's sizing runs about 4 sizes smaller than UK sizing for the same actual garment size, while EU sizing runs about 28 sizes larger than UK. These are standard approximations — cut, brand and style all affect real-world fit, so use this as a starting reference alongside a specific brand's size chart where available.
