How Kate Middleton Paid Tribute to Princess Diana and the Queen Mother at the State Banquet

Kate Middleton arrived at Buckingham Palace for the State Banquet in honor of US President Donald Trump's UK visit on Monday, and she found the perfect dress for the black-tie occasion. She walked side by side with the US Secretary of the Treasury, Steven Mnuchin, in a white gown by Alexander McQueen, one of the Duchess of Cambridge's go-to designers. Her long, pleated dress with cap sleeves flowed across the floor as she made her way into the event with the rest of the attendees, including Prince William, British Prime Minister Theresa May, and the host, Queen Elizabeth II.

The stunning mom of three paired the McQueen dress with Princess Diana's Lover's Knot tiara and sapphire and diamond earrings lent from the Queen Mother's collection. In fact, the late Queen Mother, aka Queen Elizabeth II's mom, was photographed wearing the same earrings in 1986, and they still look the same. See Kate's gorgeous ensemble ahead, and see how she paid tribute to the women who came before her.
