SAINT LAURENT’s heart-shaped ‘Loulou’ sunglasses take inspiration from its founder’s favorite motif and have amassed a host of fun-loving fans – among them, Miley Cyrus, Salma Hayek and Paris Hilton. This pair is made from silver-tone metal and black acetate. They’re fitted with smoked protective lenses and adjustable nose pads, so they’ll sit comfortably.
