It's no wonder everyone is a fan of Tom Ford's sleek and stylish Whitney Sunglasses. The large round gradient lenses are chic and trendy, while the contoured plastic rims makes them particularly flattering for square and oval face shapes. We love the modern look they lend to any ensemble, whether it's cool and casual or super sophisticated. They come in brown, dark brown, champagne and olive.
