Do These Clothes Run Small or Large? Find Out Instantly with Tellar.co.uk

The technical reality: There is no global sizing standard. Brands independently decide their fit profiles. Some brands (like Zara or Reformation) are known for running small, while others (like Nike or H&M) can run larger than expected. Even within a brand, vanity sizing and target demographics affect sizing (e.g., teenage-focused brands often fit smaller).
