Catherine was seen wearing a black polka dot skirt suit in 2007 at an Art opening. Since then she has worn the suit many times. Most recently we saw the suit in November 2015, when she visited French Embassy in London to sign the condolence book. The ensemble consists of a black lapel collar jacket with full sleeves and a pencil skirt. The origin of the skirt suit is unknown.
