Just a few months after walking down the aisle at Westminster Abbey in her wedding to Prince William, the then–Duchess of Cambridge made her first-ever appearance at Trooping the Colour in a white Alexander McQueen coatdress.

She coordinated her outfit with a black net hat.

The following year, Kate embraced royal blues in a floral long-sleeved dress from Erdem.

She paired the look with a ribbonlike fascinator and pearl drop earrings.

While pregnant with Prince George, Kate attended the 2013 Trooping the Colour in a baby-pink outfit by Alexander McQueen.

Her coatdress featured a large Peter Pan collar and pearl buttons.

Kate once again opted for Alexander McQueen in 2014, when she wore a silvery-blue brocade skirt suit.

She added a matching floral fascinator from Jane Taylor.

Kate continued the blue theme the following year, in a coatdress with a blue-and-white floral pattern, designed by Catherine Walker.

Her tilted white hat adorned with spiraling feathers made a major fashion statement.

2016’s Trooping the Colour marked the first event attended by Kate and William’s children, Prince George and Princess Charlotte. Kate looked lovely with her one-year-old daughter in a white coatdress by Alexander McQueen, which she’d previously worn to Charlotte’s christening.

The then-duchess embraced spring with a wide-brim hat adorned with a rose.

Kate looked pretty in pink the following year in another monochromatic look. Her long-sleeved dress hailed from Alexander McQueen, while her fascinator was designed by Jane Taylor.

She also accessorized with diamond drop earrings.

Kate once again matched with Charlotte in a bespoke icy-blue Alexander McQueen dress.

Her light blue fascinator featured a small white floral detail.

Her Philip Treacy hat perfectly matched the rest of her outfit, too.

After a two-year absence from Trooping the Colour—the event was downsized in 2020 and 2021, due to the COVID-19 pandemic—Kate returned looking refreshed in a white Alexander McQueen coatdress.

She added a pop of color with her navy blue hat, which coordinated with her sapphire jewelry.
