The COS womenswear team exaggerated the silhouette of the classic waistcoat when creating this modern piece. Offered in an enduring black hue, it's knitted from soft NATIVA™ wool and designed with a V-neckline, front and back darts to subtly define the waist and a longline hem that elongates the form. Style it as a three-piece suit with the coordinating blazer and trousers.
