The singer and Fenty founder arrived Cipriani Wall Street in New York City on Thursday night for her 3rd annual Diamond Ball to benefit her charity, the Clara Lionel Foundation, and she looked gorgeous. For her big event, Rihanna wore a black off-the-shoulder high-low gown from Ralph & Russo Couture. In a somewhat unusual move, she paired the dress with sheer tights, but it only made her eye-catching ensemble that much more dramatic. The R&B star accessorized her look with strappy sandals, and in true Rihanna form, a lot of diamonds. She wore a two-tiered choker that perfectly accented the gown. Rihanna kept her beauty look simple, wearing her long hair down in waves and opting for a strong eye makeup look and glossy lips.
