These refined pieces are a sophisticated choice for more formal events, with a sharp, slim fit, double-breasted fastening. The wool-silk fabric gives these jackets a delicate texture, enhanced by the noticeable sheen from the silk. It wouldn't be a Tyrwhitt jacket without our hallmarks. Think impeccable AMF stitching at the lapel, collar and pockets, corozo nut buttons, and our exclusive lapwing lining.
