    Variability and caveats

    When COS can feel different from the usual sizing tendency

    Cut

    Relaxed cuts usually add ease, so they can feel roomier than the brand’s baseline.

    Fabric stretch

    Fabric stretch changes how strongly the sizing tendency shows up: more give softens it, less give makes it more obvious.

    Styling

    This brand is fairly consistent, but styling can still shift the feel when a piece is meant to be sharply fitted or deliberately oversized.

    COS uses generous, architectural fit blocks inspired by Scandinavian minimalism. Their oversized pieces are designed to drape, so stay true to size for the intended look.
