Though Princess Diana’s life was tragically cut short, her legacy continues to live on in many ways — one of which being her iconic style.

Part of what made her fashion so memorable was her ability to wear a glamorous ball gown one day and an oversized sweatshirt the next, with both looks being equally captivating. Throughout her time as Princess of Wales, Diana developed relationships with designers like Catherine Walker and Versace, but some of her most casual moments have sparked massive trends, such as the recent resurgence in athleisure. No matter what she wore, Princess Diana embodied a timeless elegance that will continue to have influence for decades to come.

Keep reading for a look back at some of Princess Diana’s best fashion moments.

The blue suit that Princess Diana wore for her engagement photos with Prince Charles was chosen in quite the roundabout way. The Royal Style in the Making fashion exhibition, which was presented in 2021 at the royal’s former home of Kensington Palace, revealed that the then-19-year-old had first visited the Bellville Sassoon shop, but wasn’t finding anything she liked. The sales associate, who didn’t recognize her, suggested she try the nearby department store.

​​”You can imagine how Belinda [Bellville] and David [Sassoon] felt when they realized the future Princess of Wales had been turned away,” curator Matthew Storey told PEOPLE. The Princess and her mother ended up returning to the Bellville Sassoon shop and selecting the blue suit, sparking a years-long collaboration between the brand and Princess Diana.
