Similar: The Duchess of Cambridge and Princess Diana wore similar hats while on their official visits to Canada
The idea of teaming her white Reiss dress with a red hat was a huge success and went down well with her Canadian hosts.
It proved the Duchess of Cambridge is fashion conscious and clearly considers each outfit before she deciding to wear it.
But it also shows she knows a little bit about history too as she wore a similar outfit to that of her husband's mother, Princess Diana - who would have been Kate's mother-in-law - when she visited Canada in 1983.
Both sported red hats with white dresses during their official visits but Princess Diana made a slightly bolder statement by wearing a matching red scarf.

She completed the look with red court shoes and an Anya Hindmarch Fan clutch from the British label's spring/summer collection.
The Duke and Duchess of Cambridge are on a nine-day tour which spans seven cities and five provinces.
As part of their trip the couple will include stops in Alberta, the Northwest Territories and Quebec before jetting off to Los Angeles.
Their tour is much shorter than Prince Charles and Diana's who spent 18 days in the Commonwealth country.

Princess Diana was the main attraction with thousands of people waved flags and shouted the slogan 'We Want Di'.
Prince William's new wife has also been a real crowd pleaser and her wardrobe had been one of the main topics of discussion.
She has a few old favourites among the 30 outfits she has packed for her trip to the U.S. and Canada.
The white dress she chose for a citizenship ceremony in Ottawa was the same one she wore for her official engagement portrait with Prince William last November.
The 29-year-old used red accessories to finish off the look. Her hat by her favourite milliner Sylvia Fletcher at Lock & Co, featured Canada's national symbol, the maple leaf, as did her diamond brooch, which was borrowed from the Queen.
