16 Times the Royal Family Paid Tribute to Queen Elizabeth II Through Fashion

During a visit from King Willem-Alexander and Queen Maxima of the Netherlands, Middleton wore a blue Alexander McQueen dress with the Lover's Knot tiara, which was passed down to her after Princess Diana's death. She wore it for the first time at Buckingham Palace in 2015, and it has since become one of her favorite pieces to accessorize with on special occasions.
