Princess Diana made her only Met Gala appearance in 1996, shortly after divorcing then-Prince Charles. She wore a blue lingerie-inspired silk dress.

At her one and only Met Gala appearance, Princess Diana made a statement of post-divorce independence by altering her Dior gown into something far more risqué than its designer had intended.

Would it surprise you to learn that Princess Diana attended the Met Gala only once? The Met Gala is basically the Super Bowl of fashion and Lady Di was always a style MVP, but, for whatever reason, the 1996 event was the only Met Gala she ever attended. That said, Princess Diana's one Met Gala look was quite enough to make a major splash.
