Perhaps most memorably, Princess Diana also attended in 1995, looking stunning in a lace-trimmed Dior dress. What's more, US Vogue editor and chair of the event Anna Wintour even has her heart set on more royal guests at the gala. She told the Today show: "I would love to have the Duchess of Sussex and the Duchess of Cambridge together," she said. "That would be my dream couple. They could leave their husbands at home. It’s the two of them I want." Scroll down to see the Met's most memorable royal moments…
