Politics, panache and pillbox hats - the fashion of Expo 67
The uniforms were beautifully cut and powder blue. The gloves were white.
And the hats? The tri-coloured pillboxes were meant to stand out in the huge crowds that came to Expo 67 in Montreal, and to allow people to spot the exuberant, helpful young women who were cast as the fair's official guides and Canada's ambassadors to the world.
More than 50 million people made the pilgrimage to Montreal - to what is considered the most successful World's Fair in history.
Ninety pavilions celebrated provinces, nations, themes and industries. Visitors had their special Expo passports stamped at each, and could feel as if they had travelled the world in a day.
Fashion didn't have its own dedicated pavilion, but it was everywhere at Expo. In the giant sunglasses and elegant scarves, the pop-art psychedelic dresses and blue denim jeans worn by visitors. On the models roller-skating down the runways of the many pavilions. And most of all, in the designer-made hostess uniforms.
This was Montreal, of course, and design really mattered.
Many of the clothes that helped define Expo ended up in the vaults of Montreal's McCord Museum of Canadian History. Now, for the first time in half a century, the garments can be seen in an exhibit that shines a light on that remarkable time through the lens of fashion.
