Prince Louis was christened on Monday in a very special garment.
The young royal wore a handmade replica of the Royal Christening Robe. According to the Palace, the original robe was made in 1841 for the christening of Queen Victoria's eldest daughter—Victoria, Princess Royal. Truly fit for royalty, the robe was made with fine Honiton lace lined with white satin.
The robe was handed down for many generations and was worn by Queen Elizabeth, her children—including Prince Charles—and her grandchildren, including William and Prince Harry.
After years of wear, The Queen retired the garment and commissioned Angela Kelly to make a handmade replica. Her Majesty's youngest grandchild, James, Viscount Severn, was the first member of the royal family to wear the new robe, which he donned during his 2008 christening at a private chapel within Windsor Castle.
Prince George and Princess Charlotte also wore the replica during their christenings in 2013 and 2015, respectively.
Kate arrived at The Royal Chapel at St. James's Palace with her little one sound asleep in her arms. Meanwhile, William held George and Charlotte's hands. In addition to the proud parents, Charles and Duchess Camilla were there as were Harry and Meghan Markle—making it the Duchess of Sussex's first royal christening. Of course, the Middletons were there, too. Kate's parents, Carole Middleton and Michael Middleton, attended as did her brother James Middleton. Sister Pippa Middleton, who is pregnant, and husband James Matthews were there, as well.
Louis' six godparents are also attending.
However, Queen Elizabeth and Prince Philip did not attend the big day. This is reportedly not due to health concerns.
