Every Photo Proving Prince George and Princess Charlotte Are the Ultimate Page Boy and Bridesmaid
The siblings looked adorable in outfits by Pepa and Co. as they prepared to make their way down the aisle at St. Mark's Church in Englefield.
Charlotte wore an ivory silk dress with a frilled collar, a nude pink sash and matching trim across the sleeves and neckline with hand-embroidered detailing. The bodice featured a vintage style lace panel and the dress carried a net petticoat with lace trim underneath. She also wore ivory opaque tights and beige soft leather shoes.
George wore an ivory double-breasted silk pleated shirt with Peter Pan collar and coordinating trim detail paired with knickerbockers in pale olive Vienne silk and a matching cummerbund.
Charlotte, who also wore a floral headband, flashed a big smile with mom Kate as the little bridal party members prepared to walk down the aisle.
After the ceremony, wedding guests told reporters that the children were "very" well-behaved during the ceremony.
George adorably channeled dad William, who was a page boy in his uncle Prince Andrew's wedding to Sarah Ferguson in 1986. And Charlotte was oh-so-sweet in her matching bridesmaid dress.
Pepa Gonzalez told PEOPLE, "It was truly an honor to be part of this project and I was excited to take on the commission for all bridesmaid and page boy outfits."
The designer added, "We have such fond memories of designing these bespoke garments for the children who all look so adorable and cute."
George was leader of the pack as they exited the church!
Prince George and Princess Charlotte took on the important roles of page boy and bridesmaid at the royal wedding.
Princess Charlotte proved that she's another spare heir with a mischievous streak, appearing to stick out her tongue from inside the car as she arrived to St. George's Chapel. (Turns out, groom Prince Harry was known for pulling this move as a child!)
Here we go!
Charlotte and the other bridesmaids made their way up the stairs with the help of some of the moms!
Charlotte made sure to greet well-wishers outside the church with a wave.
George and Charlotte joined eight other little bridal party members, including several of Harry and Meghan's godchildren. The little girls wore floral crowns and white dresses, while the boys dressed in miniature versions of the Blues and Royals frockcoat, mirroring Harry's military ensemble.

The occasion marked the first time Prince George wore pants in public! (Upper-class British boys usually wear shorts until they're 8 years old!)
George was seen marching around with a smile on his face, while his sister Charlotte gives her big brother an amused look.
"George is a real star, quite the little chap," a source told PEOPLE. "He was having a great time, running around like the leader of the pack."
On Oct. 12, 2018, George and Charlotte joined the bridal party for Princess Eugenie's nuptials to Jack Brooksbank, arriving in style to St. George's Chapel with a bevy of cousins and family friends.
The kids couldn't help but goof off on the chapel steps.
And inside, too! George shared a laugh with cousin Savannah Phillips while Charlotte did her best to keep a straight face.
As with Harry and Meghan’s wedding, the children stayed in a room to the side during the ceremony, returning to escort the bride and groom back down the aisle after they signed the marriage register.
George and Charlotte, along with the other young members of the bridal party, wore looks by Amaia Arrieta of Amaia Kids. The design incorporated the Mark Bradford artwork included in the Order of Service.
While one young page boy took a fall up the stairs in the windy weather, Charlotte couldn't stop waving to the crowd.
