Kate Middleton knows how to make an impression.

The Princess of Wales stunned in a jaw-dropping red gown by Givenchy for a state banquet held at Windsor Castle on Tuesday night.

The royal accessorized with earrings from the late Queen Elizabeth’s collection, and donned Queen Mary’s Lover’s Knot tiara ― marking the first time she’s worn a tiara in nearly two years, as pointed out by People magazine.

Kate attended the dinner alongside Prince William, as well as celebrity guests like Mick Jagger and Elton John.

The dinner was hosted by King Charles and Queen Camilla in honor of French President Emmanuel Macron and his wife, Brigitte Macron, as they kicked off their state visit to the U.K.
