Kate, 30, looked beautiful in a red Alexander McQueen dress. Adding drama to the ensemble was a matching fascinator designed by Sylvia Fletcher from James Lock and Co, PEOPLE reports.
The event celebrates the 86-year-old Queen’s 60 years on the throne. A massive procession of more than 1,000 boats traveled down the River Thames into London to pay tribute.
Kate’s husband William and his brother Harry wore their military outfits to commemorate the day.
