Kate Middleton and Princess Charlotte made a vivid impression at this year’s Trooping the Colour in London.

The mother and daughter appeared at the annual event decked out in coordinated aquamarine outfits, with the Princess of Wales clad in a brightly colored coat-dress and matching hat, alongside 10-year-old Charlotte in a more muted, minty shade.

Middleton’s coat-dress was designed by Catherine Walker —a favorite of Princess Diana —while her pearl drop earrings belonged to Queen Elizabeth II.

Trooping the Colour is a yearly military parade that also serves as the king or queen’s official birthday celebration ― even though it often doesn’t fall on the sovereign’s actual birthday. The real birthday of King Charles III is Nov. 14.

Coincidentally, this year’s Trooping the Colour was scheduled for the same day that U.S. President Donald Trump held a massive military celebration and parade to celebrate the Army’s 250th anniversary. The date just so happened to coincide with Trump’s birthday, and was met with protests around the country branded as “No Kings” demonstrations.
