How Princess Diana transformed royal style

By not sticking to tradition, Diana, Princess of Wales, earned her place in the pantheon of best-dressed women in history. And it’s a position that has only been more firmly fixed in the two decades since her death, the anniversary of which is Aug. 31.

Her style evolution — from a feather-haired “Sloane Ranger” in frilly, pie-crust blouses and endless pastels to the regal woman who confidently strode in bodycon velvet, athleisure outfits, and glamorous jewels — hinged on what was some major bending of the royal rules of fashion at the time. The princess’s risk-taking moves — such as wearing denim overalls in public (the scandal!) — paved the way for Kate Middleton’s casual-glam mom style.

“Diana often didn’t wear gloves or hats, and was the first female royal to wear trousers to an evening event,” exhibit curator Eleri Lynn told WWD during a walk-through of “Diana: Her Fashion Story,” an exhibition now at Kensington Palace that showcases the most iconic looks Diana wore during public outings, as well as the reasoning behind the outfits.

“She learned the unwritten rules of royal dressing,” Lynn added, “but liked to break them sometimes.”

Blue Eyeliner

Revenge Dress

Wearing this famous black revenge dress, commissioned from Christina Stambolian, was a spectacular coup by the princess on the very evening that Prince Charles made his notorious adultery admission on television. And she didn’t stop there. … (Photo: Getty Images)

Overalls

Workout Clothes in Public

The Princess of Wales was notoriously fit, and that obviously comes from hard work at the gym. She was never shy — particularly after her separation — about wearing sweatshirts and shorts in public after a workout. (Photo: Anwar Hussein/Getty Images)
