The ring is similar to sister Kate’s wedding ring, which is a simple Welsh gold band. British royal brides have been wearing Welsh gold bands as wedding rings for nearly 100 years.
Middleton, who arrived at the church with her father, Michael Middleton, was a beautiful bride in a custom silk cotton lace gown by Giles Deacon.
Her young nephew and niece, Prince George and Princess Charlotte, also joined the wedding party, acting as a page boy and bridesmaid, respectively. Naturally, they stole the show — even if they had to be shushed by mum Kate, who ushered them into the church along with the other children.
After getting the children settled, Kate greeted her sister and father at the entrance of the church and helped smooth out her sister’s dress.
Guests leaving the party after the wedding told reporters that the ceremony was lovely.
“It was amazing,” one guest told WHO. “They were so cute. I cried. My makeup was running.” They added that George and Charlotte were “very” well-behaved.
Wedding guests included Princess Eugenie, Prince William and Prince Harry — who later brought his girlfriend Meghan Markle to the post-church evening reception at the Middleton family’s home.
Matthews, 41, proposed to Middleton in July 2016 in the picturesque Lake District of northwest England.
Matthews manages a hedge fund and is chief executive of Eden Rock Capital Management Group, which he established more than 10 years ago.
