A brand whose aesthetic has been so influential that it’s hard to remember what went before. But when COS launched in 2007 against a backdrop of fast, trend-led fashion, its focus on minimal pieces at accessible prices was a breakthrough moment. With a focus on style over trend, it heralded a new era for interesting, modern, considered design and changed our wardrobes for the better, forever.
