It’s His Royal Highness Prince George of Cambridge‘s big day! The young prince celebrated his christening at the Chapel Royal in St. James’s Palace wearing a handmade replica of the royal christening robe designed by the Queen’s dressmaker, Angela Kelly, according to the British Monarchy. But not all eyes were solely on the Royal Baby — new mom Catherine also stole the show with her cream ruffled Alexander McQueen suit paired with a rose-adorned Jane Taylor fascinator and her signature nude L.K. Bennett pumps. Prince George and Kate were joined by Prince William, both sets of grandparents, along with his aunt Pippa Middleton and uncles Prince Harry and James Middleton. This is baby George’s first public appearance since we were first introduced to the little bundle of joy back in July and comes just hours after the announcement of his seven godparents, who were also in attendance for the occasion. Congratulations to the little prince and his parents!
