Queen Elizabeth II looked radiant in a peach coat and matching hat at the society wedding of Lord Mountbatten’s great-granddaughter Alexandra Knatchbull. She is the daughter of Lord and Lady Brabourne and got married at Romsey Abbey in Hampshire on Saturday. The 33-year-old is a forensic accountant and theology graduate of Regent’s Park College Oxford and also the goddaughter of Princess Diana.

Prince Charles, who is a close friend of Alexandra’s parents, gave away the heiress. The 67-year-old prince looked handsome in a gray-three piece suit and accompanied her down the aisle to her waiting fiancé, Thomas Hooper. Alexandra looked stunning on her big day in a white satin wedding dress with lace embroidery.

Meanwhile, the nonagenarian queen was accompanied by her husband Prince Philip and daughter Princess Anne for the wedding ceremony. Elizabeth glowed in a peach floral dress, which she paired with a matching coat. The coat featured long sleeves, collar, chunky pearl buttons and oversize pockets.

The queen accessorized with three-string pearl necklace and matching earrings and a gold brooch. She also wore white gloves, carried her black Launer handbag and wore her trusted pair of black shoes. Elizabeth wore a peach asymmetric hat with matching floral accents and completed her look with a slick of deep pink lipstick.

Anne also looked chic in a pale pink suit, matching coat and a white blouse. She wore a matching two-tone hat, black gloves and a matching bag. Like her mom, she also accessorized with pearl earrings, a matching necklace and a gold brooch. Anne completed her look with black shoes.

Alexandra’s dad Norton Brabourne, is the godson of the Duke of Edinburgh and one of the Duke of Cambridge’s godfathers. Charles was the best man in Norton’s wedding to his wife, Lady Penelope. Alexandra’s brother Nicholas attended school with Prince William and was a peer mentor to him throughout his studies at Eton.

Queen Sophia of Spain and the former King Constantine II and Queen Anne-Marie of Greece had arrived earlier in the week in order to celebrate the occasion.
