Kate Middleton and Meghan Markle wear their finest for first joint appearance since split

Royal fans just got a double dose of style!

Catherine, Duchess of Cambridge, and Meghan, Duchess of Sussex, stepped out in London Monday to celebrate Commonwealth Day, and looked as regal as ever in bold, jewel tone ensembles.

The annual event, which honors the 53 nations in the Commonwealth, typically draws multiple members of the royal family. This year's service marked the first joint appearance for the duchesses and their husbands since Meghan and Prince Harry announced they would be stepping back from their royal duties.

The Duke and Duchess of Cambridge returned from their three-day visit to Ireland just in time for the event. The former Kate Middleton turned heads in a burgundy coat dress with velvet trim, a matching hat with striking floral detail and matching shoes. Prince William coordinated with his wife's color scheme, opting for a burgundy, polka-dot tie to go along with his navy suit.

The mother of three also added a touch of fun with a twisted chignon and kept her makeup simple, opting for glowing skin and a soft pink lip.

The look was somewhat reminiscent of the red coat and hat the 38-year-old wore to the 2019 Commonwealth Day event.

Meanwhile, the former Meghan Markle held hands with Prince Harry as they arrived at the event, and looked gorgeous in an emerald green midi dress with a cape and a matching hat with mesh detail. She accessorized with a pair of nude pumps and a hunter green mini purse.

The Duke and Duchess of Sussex are back in London for their final engagements as senior royals, and the former Meghan Markle is definitely making every outfit count. The 38-year-old swept her hair up in a sleek bun and wore a smokey eye and glossy lips to complete the look.

Last year, the duchess attended the event in a chain-printed Victoria Beckham dress worn under a long white coat.

In 2018, both couples attended the annual event just weeks before the Duke and Duchess of Sussex got married.

It was the former Meghan Markle's first official engagement with the queen, and she looked classic in a navy dress worn under a white coat and matching beret. The Duchess of Cambridge also looked stylish in a navy blue coat dress and coordinating hat.
