The COS womenswear team turn traditional tailoring codes on their head with this directional single-breasted bustier. Crafted from RWS-certified wool, it's designed for a slim shape with a bandeau neckline that's internally elasticated for support. Design details include the bust and waist darts, slightly curved hem and the flapped pockets that nod to classic tuxedo jackets. Create a modern look by wearing it with the matching pants or a skirt.
