Saint Laurent is the fashion world's undisputed master of suiting, as this black blazer demonstrates. Crafted in Italy from wool twill with a touch of cashmere blended in for warmth, it's meant to be slightly oversized and boxy, per the brand's signature silhouettes. Padded shoulders help to structure its shape, while a smooth silk lining ensures a clean, crease-free fit. We love the glamorous addition of golden buttons.
