COS takes its name from the phrase “Collection of Style.”
The H&M Group brand was created in 2007 as a more design-led alternative within the group’s portfolio. Its collections are known for clean lines, modern proportions and clothing intended to remain useful beyond a single season.
The name is not an abbreviation for a city, designer or fabric. It is a shortened form of “Collection of Style,” a phrase that communicates the label’s focus on curated, contemporary wardrobe pieces.
COS is one of several brands operated by H&M Group, alongside H&M, ARKET, Weekday, Monki and & Other Stories. These brands are differentiated by design identity, customer segment and price level.
