Kate Middleton and Meghan Markle brought their fashion A-game to the Platinum Jubilee celebrations.

Queen Elizabeth’s family gathered for a special service of thanksgiving at St. Paul’s Cathedral on Friday as part of the weekend of festivities honoring the monarch’s 70-year reign. While many royal women opted to match the Queen in blue on Thursday for Trooping the Colour, there was a rainbow of colors present for the church ceremony — including pink for Zara Tindall, orange for Princess Eugenie and blue for Princess Beatrice.

Meghan arrived with Prince Harry in a stone white belted coat dress with a dramatic collar and a matching wide-brimmed hat, with her hair swept into an updo. The Duchess of Sussex, 40, carried gloves and also sported one of her go-to pairs of earrings: the Snowflake Snowstorm earrings by Birks. She previously wore the earrings on a number of occasions, including the Commonwealth Day service in 2020, which marked her last event with the royal family before she and Prince Harry stepped back from their senior roles and relocated to California.

Kate, 40, brought a hint of sunshine on a cloudy day in a pale yellow ensemble with a defined waist detail by Emilia Wickstead along with a matching hat featuring a hidden floral detail under the slanted brim by Philip Treacy. She carried a clutch as well as a pair of gloves.

The Duchess of Cambridge also sported a special pair of earrings: the Bahrain Pearl Drop Earrings, a pair straight from her grandmother-in-law’s jewelry box that she has borrowed before.

Prince William and Kate sat on the opposite side of the aisle from Meghan and Harry. The service marked the first time that the Cambridges and Sussexes have been seen together as a foursome since Commonwealth Day in March 2020, which was Harry and Meghan’s final royal appearance before they stepped back from their roles as senior working royals. The Duke and Duchess of Sussex, who now live in California, arrived in the U.K. on Wednesday with their two children — Archie, 3, and Lili, who turns 1 on Saturday.

Several royal family members were in attendance on Friday, but the guest of honor, Queen Elizabeth, was noticeably missing. The palace announced on Thursday that the monarch would not be attending due to feeling “some discomfort” at Trooping the Colour due to ongoing mobility issues.

“Taking into account the journey and activity required to participate in tomorrow’s National Service of Thanksgiving at St Paul’s Cathedral, Her Majesty with great reluctance has concluded that she will not attend,” the statement said.
