Offering sharp lines and a frame-defining structure, a well-cut black waistcoat is highly prized by great dressers – with good reason. Moss 1851’s tailored-fit design is kept classic with its pure-wool construction, tonal backing and covered buttons. Formal all the way, it will look the part styled simply with a white shirt and black trousers, or you can build it into a three-piece to hit that dress code just right.
