It鈥檚 a big day for Meghan Markle! Prince Harry鈥檚 fianc茅e has slowly but surely been immersing herself into life with the royal family: She聽had聽her first official engagement appearance with Kate Middleton last month and reportedly was聽baptized into the Church of England聽as a show of respect for Queen Elizabeth II. Now, she鈥檚 checked off one more milestone with her first-ever appearance with the Queen.

Forfor its Commonwealth Day church service at Westminster Abbey, Markle opted for a cream tailored coat (not unlike the affordable style future sister-in-law Kate Middleton recently sported) and a navy dress from British designer Amanda Wakeley (a favorite of Princess Diana), plus a beret by Stephen Jones. She finished the look off with a pair of blue pumps (oh-so similar to Markle鈥檚) and a leather Mulberry clutch.

Middleton also opted for a hat, choosing a wide-brim Lock and Co. style to match her elegant navy Beulah London coat and dark dress.

The Queen (who looked rather smart herself in a regal burgundy coat with a matching floral topper, a printed dress, and pearls), presides as head of the Commonwealth, an intergovernmental organization comprised of 53 member states.

The family, also joined by Princes Harry, William, and Charles, as well as the Duchess of Cornwall, Camilla, was treated to a performance from Liam Payne as well as a speech from the Queen, who noted the importance of the group. 鈥淪hared inheritances help us overcome differences so that diversity is a cause for celebration rather than division,鈥 she said.

Kudos to Meghan for knocking this one out of the sartorial park!
