Oh Canada! Will and Kate Celebrate

July 1, 2011— -- Hundred of thousands of revelers helped Prince William and Kate Middleton celebrate Canada's independence day.

After arriving in a horse drawn carriage, the prince greated the massive crowd in french.

Kate embraced Canada Day in a white dress, red pumps and a red hat adorned with maple leaves, the nation's symbol. Royal watchers might recorgnize that dress. The duchess recycled it from her personal wardrobe, having worn it in her official engagement portrait.

Kate also wore a diamond maple leaf broach, on loan from Queen Elizabeth. The queen wore the pin during a visit to Canada in 1951.

"It's been a great wardrobe for a great kickoff of the royal tour," royal expert Nicholls told ABC.

Traveling without a personal dresser, or lady-in-waiting, the duchess will rely on her longtime London hairdresser, James Pryce, who styled her wedding and engagement hair, for both fashion and hair advice.
