COS was founded in 2007 as an H&M Group fashion label focused on modern, minimalist design.
The brand name comes from “Collection of Style,” and COS was created to offer elevated everyday clothing with clean silhouettes and a more considered design language. It occupies a different position from the main H&M brand, with an emphasis on materials, construction and timeless forms.
COS expanded internationally through stores and digital retail. Its collections cover womenswear, menswear and accessories, and the label became particularly associated with architectural shapes and understated presentation.
COS is sometimes confused with ARKET because both offer minimalist products and belong to H&M Group. COS predates ARKET: COS launched in 2007, while ARKET was introduced in 2017.
