Wool/cashmere blend olive turtleneck sweater style dress by Ralph Lauren, with ribbed cuffs and collar.
Not many women can wear that type of dresses but Kate can. However it enhances a bit too much her lack of hips.
1- Kate wore it on 21st December 2011 at Centrepoint in London, a charity that helps homeless youngsters get back on their feet and find jobs and shelter. The dress was accessorized with a black belt.
