Middleton memorably wore this red, asymmetrical Preen dress for a reception at the Government House on 26 Sept., 2016, during her royal visit to Canada. Pinned on the right side was the Maple Leaf brooch, which was originally gifted to the Queen Mother by King George VI in 1939 and was first worn by Elizabeth when she was still a princess in 1951. Middleton is not the only royal to have been loaned the brooch, as Queen Elizabeth II also allowed Camilla Parker Bowles to wear it.
