Kate Middleton Wore Princess Diana’s Favorite Tiara in London

Catherine, Duchess of Cambridge, has finally shaken up her tiara game. On Tuesday night, the mother of Prince George and Princess Charlotte wore the Cambridge Lover’s Knot tiara, full of pearls and diamonds, to the annual Diplomatic Reception at Buckingham Palace. This particular tiara was a favorite of her late mother-in-law, Diana, Princess of Wales.

She didn’t, however, shake up her style game. Based on her street style, the 33-year-old mum doesn’t have a magical wardrobe filled with the latest designer clothes or a key to a vault with the most precious jewels in the world. In fact, she does an awesome job of looking like she doesn’t have access to fresh-off-the-runway gowns and priceless diamonds and pearls. Because Kate Middleton — sorry, Her Royal Highness — could traipse around a palace in the most elegant and precious items ever made if she really wanted to. And yet, she loves to wear the same thing on repeat, like the baby blue Alexander McQueen dress she chose to wear with her new tiara.
