COS began life in 2007 as a brand devoted to simple, functional design that is driven by perennial style rather than annual fashion trends. The brand has stuck to this mission, producing chic, minimal clothing season after season for both men and women. The label also incorporates accessories and there is a hosiery range too. The hosiery line includes contrast colour socks in colour combinations like grey and neon yellow or black and deep red, as well as striped and plain colour options. There are wool tights in many colours, cotton tights and ribbed ankle socks, as well as unique sock designs with sheer panels.
