Saint Laurent Rectangular tortoiseshell acetate glasses

Saint Laurent's brown tortoiseshell glasses feature a slightly oversized rectangular frame as a modern departure from traditional silhouettes. They're simply engraved at the temples with the house's minimalist logo – designed by former creative director Hedi Slimane as part of his contemporary vision for the French house. Wear them with fluid tops and flared trousers as part of an unstudied workweek look.
