Since Kate Middleton married Prince William in 2011, she has only worn a tiara a handful of times. Over the course of her now 14-year royal career, the then-Duchess of Cambridge, now the Princess of Wales, has sported just four different tiaras publicly: the Cartier Halo, which she wore on her wedding day; the Lotus Flower, which was notably one of Princess Margaret's favorites; the Lover's Knot, which carries a special association to Kate's late mother-in-law, Princess Diana; and the Strathmore Rose tiara, which hadn't been worn for nearly a century before Kate sported it once in 2023. Here, take a look back at every time Kate Middleton—now known as Catherine, Princess of Wales—has worn a tiara.
