What does the acronym COS stand for in H&M Group’s fashion brand?

COS stands for “Collection of Style.”

The name belongs to H&M Group’s fashion brand that launched in 2007. COS was positioned as a design-led label offering modern clothing with an emphasis on clean lines, tailoring and long-lasting wardrobe pieces.

The acronym is sometimes treated as if it were an abbreviation for a Swedish phrase, but the official expansion is the English “Collection of Style.” Its first store opened in London, helping establish the brand’s international and design-focused identity.

COS operates separately from H&M, even though both belong to the same corporate group. Their product ranges, store environments and pricing are different, which is why the acronym identifies a distinct brand rather than an H&M collection.
