Saint Laurent's romantic edge is beautifully showcased in this navy cashmere cardigan. It's knitted in Italy to a relaxed silhouette and features detachable antiqued silver-tone metal heart pins on the front patch pocket – lifted from the founder's illustrated personal love notes – and finished with ribbed-knit detailing. Layer it over a casual T-shirt, jeans, and velvet boots for a pick ‘n’ mix approach.
