How do US and European clothing sizes compare?

European sizes are typically 30 sizes larger than US women's sizes (US 8 = EU 38) and 10 sizes larger for men's suits (US 38 = EU 48). However, this varies by garment type. Pants, shirts, and dresses may use different conversion formulas. Always check the specific brand's size chart as manufacturers vary.

Why do clothing sizes vary between brands?

Clothing sizes are not standardized globally or even within countries. Brands use different fit models, vanity sizing (making sizes smaller than standard), and target different body types. Measurements can vary by 1-2 inches between brands for the same labeled size. This is why trying on clothes or checking exact measurements is important.

What is vanity sizing?

Vanity sizing is when brands label clothes with smaller size numbers than the actual measurements would indicate. A modern US size 8 might have the same measurements as a size 12 from 30 years ago. This marketing practice makes customers feel better about their size but creates confusion when comparing brands or vintage clothing.
