This is the COS design team's more dressed-up take on the laid-back T-shirt dress. Crafted from stretch-cotton jersey, it's shaped with ruching at the sides and has an asymmetric midi hem that enhances the floaty silhouette. Wear it with mules and a pair of statement earrings.
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.
