Saint Laurent SL 78 cat-eye sunglasses feature a bold, vintage-inspired silhouette with a luxurious tortoiseshell acetate frame in warm amber-brown tones. The iconic YSL monogram plaque adorns the temple hinge, while the slender arms bear the 'SL 78' model code—a signature detail referencing the brand’s heritage. Green-tinted lenses provide UV protection and a subtle retro aesthetic, complementing the refined yet edgy design. Crafted with precision in Italy, the frames offer lightweight comfort and balanced weight distribution for all-day wear. The distinctive pointed outer corners and slightly upswept browline evoke 1960s glamour, making them ideal for fashion-forward individuals seeking statement eyewear. Perfect for urban street style, brunch outings, or elevated casual events, these sunglasses pair effortlessly with minimalist tailoring or boho-chic ensembles. The included black leather case and branded box reinforce Saint Laurent’s luxury positioning, ensuring both protection and presentation. A timeless piece that bridges haute couture and contemporary cool, the SL 78 remains a cult favorite among editors and influencers for its sculptural elegance and unmistakable brand identity.
