Kate Spade's Alvi cat-eye sunglasses combine a black studded acetate brow with a delicate gold-tone metal clubmaster base. The frames feature white pearl stud embellishment across the upper rim, paired with gradient blue lenses that fade from dark to light. Metal arms with subtle branding complete the refined silhouette. Style with oversized sunglasses for a bold editorial edge or pair with minimal fare for understated glamour.
