Camilla observed Armistice Day in Ottawa this year amid the official tour of Canada she's undertaken with Prince Charles. And she chose what I think is her best "memorial" hat to do so -- it's actually the same one she wore last November 11th to mark the 90th anniversary of the Armistice in France. This year she's added the cap badge of The Rifles, which she wore recently as a hat adornment as well.
Love it. The flower's audacious but not ridiculous, and the netting wrapped around the beret looks really elegant. Bravo!
