The 70s trend refuses to quit, especially when it comes to oversized shades. This season, gradient lenses are the latest incarnation. Forget rose-colored glasses…go purple instead with this pair by Dolce & Gabbana. Finish the look with beachy hair and a straw chapeau for the ultimate boho vibe. Available at Pearle Vision in Roslyn, (516) 365-4066; $399.95.
