Kate Middleton and Prince William's kids, Prince George and Princess Charlotte, have arrived at St. George's Chapel in Windsor, England, ahead of the couple's "I do's." The young royals will serve as page boy and bridesmaid, respectively. The siblings last served in a bridal party during their aunt Pippa Middleton's wedding to James Matthews last May.
George looked adorable in a miniature version of the Blues and Royals frockcoat, which draws its insignia from the Blues and Royals, an old Regiment of The Duke of Cambridge and Prince Harry. As a special memento, George has his initials embroidered in gold on his shoulder straps. His outfit was cut and made by tailors Dege & Skinner in Savile Row.
Charlotte wore a bridesmaids dress in ivory silk Radzimir, and is high-waisted with short puff sleeves and hand finished with a double silk ribbon detail tied at the back in a bow. They also include pockets and pleated skirts to create a relaxed and luxurious silhouette that were designed by Givenchy's Clare Waight Keller. Charlotte also wore a flower crown selected by Prince Harry and Meghan, which were designed by florist Philippa Craddock.
Charlotte completed the outfit with white leather Aquazurra shoes, each pair monogrammed with the bridesmaids' initials, as well as the May 19, 2018 wedding date. The shoes are a gift from Meghan to the young ladies as a special keepsake.
While the brother-sister duo were sweetly shushed by their mom at Pippa's wedding, this time around, they were total pros. George, 4, and Charlotte, 3, couldn't have looked more adorable as they waited to join the wedding procession inside the chapel.
After the wedding ceremony, George and Charlotte proudly followed behind Harry and Meghan as they left the castle.
Kate and William's third child, Prince Louis, was not expected to attend, as ET learned that the 3-week-old royal would be staying home.
Kensington Palace officially revealed in April that William would also have a role in Harry's wedding, serving as his brother's best man, just as Harry did during William and Kate's wedding in 2011.

Meghan, meanwhile, will not have a maid of honor. "She has a very close-knit circle of friends and she didn't want to choose one over another," a spokesman from Kensington Palace told ET earlier this month. "All have been actively involved in helping her prepare for the day and will be there in the days beforehand. She's very happy to have their support."
