In a moment of mother-daughter twinning, Kate Middleton and Princess Charlotte opted for coordinating outfits at this year’s Trooping the Colour parade.

The Princess of Wales wore an aquamarine coat dress by Catherine Walker to the event, featuring ivory lapels and cuffs. A matching hat by Juliette Botterill Millinery with floral detailing, as well as drop pearl earrings once belonging to the late Queen Elizabeth, were her accessories of choice. As the colonel of the Irish Guards, the royal also wore the Irish Guards Regimental Brooch pinned to the front of her dress.

Her daughter Charlotte mirrored her mother’s timeless style in a lighter-hued dress with a white hem at the neckline and a white bow at the waist. A matching white bow in her half-up, half-down hairstyle, and white ballet flats, polished the two-toned look off.

Looking to the past, Middleton has taken sartorial inspiration from her late mother-in-law, Princess Diana, on numerous occasions, and this look also felt reminiscent.

At the same event in 1988, the people’s Princess also wore a Catherine Walker coat dress—hers in teal—with ivory detailing down the collar and on the cuffs. She paired the dress with a Phillip Sommerville hat as well as a three-row pearl choker and earrings.

In their very own family twinning moment, a young Prince Harry matched his mother with a white shirt under matching teal shorts and suspenders.

The ceremonial parade celebrates the British monarch’s birthday with a military showcase. While it is not the King’s real birthday, it is a tradition that dates back to the 18th century.

This year’s event happens to be Middleton’s first since her cancer went into remission, making it particularly meaningful.
