Prince William and Kate Middleton, the Prince and Princess of Wales, celebrated their 15th wedding anniversary with a family portrait taken during their recent holiday in Cornwall. In the photo, Kate, 44, looked effortlessly elegant in a £298 striped cashmere sweater from Veronica Beard and £119 Blexley Cigarette Trousers from Holland Cooper, while William, 41, opted for a £90 khaki polo shirt from Hackett. Their three children, Prince George, 12, Princess Charlotte, 10, and Prince Louis, 8, were also dressed for the sunny seaside getaway. The couple's anniversary is particularly poignant as Kate has recently completed chemotherapy treatment for cancer, a journey they have navigated together. Their relationship began at university, where they became friends before falling in love, leading to a grand wedding at Westminster Abbey on April 29, 2011. This anniversary marks a significant milestone in their lives, reflecting both their personal challenges and the joy of family.
