Shein vs Zara Sizing

Shein and Zara represent two different approaches to fast fashion — Chinese manufacturing versus European design — and their sizing reflects those origins. Shein uses Asian sizing that runs one to two sizes smaller than US standards, while Zara uses European sizing that runs about half a size small. For a US Medium, you might need a Shein Large but a Zara Medium or Small. The price points are vastly different, and so is the fit — Zara's cuts are more structured and tailored while Shein's tend to be looser and more casual. Shoes are measured in EU sizes on both platforms, but Shein's shoes run narrower. Our converter shows your exact size at both stores across all categories so you can shop both with confidence.
