Princess Charlotte was every bit Kate Middleton’s mini-me at this year’s Trooping the Colour celebration.

The mother-daughter duo matched in bright aquamarine hues for the annual event, which honors the reigning monarch’s birthday with a grand display of military pageantry.

While Charlotte often coordinates her look with her brothers, Prince George and Prince Louis, for royal outings, this time she took a cue from her mother’s signature flair for a standout sartorial moment and opted to mirror her fashion rather than her siblings’.

For the parade, which traditionally sees members of the royal family arrive in horse-drawn carriages, the Princess of Wales wore a striking blue-green and ivory coatdress by Catherine Walker. Ever the fan of a good accessory, she completed the look with a wide-brimmed Juliette Botterill hat topped with a sculptural flower, the Irish Guards Regimental Brooch, and drop pearl earrings that belonged to the late Queen Elizabeth.

She paired her ensemble with nude pointed-toe pumps that grounded her outfit.

Charlotte echoed her mother’s palette in a light aqua dress featuring a crisp white bow at the waist, which matched the ribbon tied into her signature braided half-up, half-down hairstyle.

Following in her mom’s footsteps, she finished her look with classic white ballet flats.

Trooping the Colour, which is also known as the King’s Birthday Parade, is a tradition that dates back to King George III in the 18th century. Though King Charles won’t turn 77 until November 14, the June ceremony serves as the sovereign’s official birthday celebration every year.
