Costume change number one done!

Duchess Kate and Prince William touched down in Ottawa, Ontario on Thursday afternoon -- and for their hotly anticipated arrival in Canada, Kate switched into a different ensemble than the one she wore boarding the plane in London.

It marks the first day of the royal newlyweds' 11-day tour of North America, with eight days in Canada and three in California.

After wearing a dark navy Roland Mouret "Manon" dress and a SMYTHE One Button Blazer at Heathrow airport, the slim 29-year-old Duchess disembarked in Canada in a navy, lace Cecile shift scoop-backed dress by Erdem Moralioglu featuring sheer lace sleeves with a scallop detail.
