Duchess of Cambridge, and wife of Prince William, Kate Middleton looked sensational dressed in a grey knee length dress, at the red carpet premiere of a documentary highlighting the threatened African wildlife. Although the weather was gloomy, and Kate wore a sad grey, but her long legs and gorgeous smile lifted the moods and spirit. The sophisticated grey number was by Matthew Williamson, with jade green beading trim and peplum detail, and Kate paired it up with matching pumps by British designer Emmy Scarterfield, and a black clutch.
