Rihanna’s Dress At The 2012 Met Gala Ball. Rihanna definitely has an edgy vibe to her style, and at last night’s Met event she was seen wearing a floor-length reptile skinned dressed designed by Tom Ford. The dress was all black, featured a scooped out back, and showed off the singer’s curves from every angle. There was even a slit on the side for added sexiness. Rihanna paired the look with dark flesh tones lips and soft neutral makeup. Look below to see her seductive edgy style for the night.
