Saint Laurent SL 231 sunglasses feature a bold rectangular frame in classic tortoiseshell acetate, combining vintage charm with modern architectural lines. The frame showcases refined craftsmanship with polished silver-tone metal accents at the hinges and temple tips, while the 'SAINT LAURENT PARIS' branding is discreetly engraved on both temples. Brown gradient lenses offer UV400 protection and reduce glare without compromising style. The slightly oversized yet balanced silhouette flatters diverse face shapes, and the lightweight acetate ensures all-day comfort. Ideal for urban streetwear, smart-casual outings, or elevated summer looks, these sunglasses embody YSL’s signature Parisian chic—elegant, confident, and effortlessly cool. Paired with the branded black box and case (visible in background), they make a luxurious statement piece for fashion-forward individuals who value heritage design and contemporary edge.
