Princess Diana's outfits are part of fashion legend from her 25 ft train to the revenge dress she wore as the world watched Prince Charles admit adultery.
She was among the most photographed woman in the world from paparazzi images to the stage managed appearances for good causes or at state banquets.
And her clothing choices have inspired generations of women looking for ideas about what to wear.
Here are some of her most iconic looks:
1. Princess Diana's Wedding Dress and Train

2. The Revenge Dress
Princess Diana was photographed in an off the shoulder black cocktail dress when she arrived at the Serpentine Gallery, in London, in June 1994.
However, this was no ordinary public appearance because Diana's husband Prince Charles had recorded interviews with journalist Jonathan Dimbleby which were broadcast that night.
The outfit, by Christina Stambolian, was daring to the point it became known in the media as her "revenge dress."
The Prince of Wales had confessed on camera to cheating on her, but only once "the marriage had irretrievably broken down," he said.
3. Princess Diana's Red and White Houndstooth Coat

The interview became famous for giving the first subtle hint that all was not well in the royal couple's relationship before they even tied the knot.
Asked whether they were in love, Diana replied "of course," while Charles said: "Whatever 'in love' means."
6. The Taj Mahal
Princess Diana made a solo visit to world famous landmark the Taj Mahal during a royal tour of India in February 1992 while Prince Charles had a separate engagement in Bangalore.
The princess was photographed alone in an image that encapsulated the rumours of their rocky marriage at the time.
Months later, biography Diana: Her True Story hit book shops with its detailed account of Prince Charles' secret affair with Camilla Parker Bowles.
Biographer Tina Brown told CNN documentary The Windsors: Inside the Royal Dynasty: "That picture of her as a lonely, neglected, beautiful girl who didn't have anyone to love her back just broke everybody's hearts.
"She knew what she was doing. And it made Charles absolutely crazy."
7. Princess Diana's First Royal Engagement
Princess Diana famously wore a strapless black taffeta dress by David and Elizabeth Emanuel, her future wedding dress designers, to a concert on March 9, 1981.
She was yet to marry Prince Charles, though they were already engaged, and she went on to tell her biographer how he was upset she wore black at Goldsmiths Hall, in London.
Diana: Her True Story by Andrew Morton quotes Diana saying: "I remember my first [royal] engagement so well. So excited.
"I got this black dress from the Emanuels and I thought it was OK because girls my age wore this dress.
"I hadn't appreciated that I was now seen as a royal lady, although I'd only got a ring on my finger as opposed to two rings.
"I remember walking into my husband-to-be's study, and him saying: 'You're not going in that dress, are you?' I replied: 'Yes, I am.' And he said: 'It's black! Only people in mourning wear black."
8. Princess Diana's Uptown Girl Performance
Princess Diana's dance performance to Billy Joel classic Uptown Girl was brought to life by season four of The Crown.
The Princess of Wales and professional dancer Wayne Sleep earned eight curtain calls with their routine, a surprise for Prince Charles' birthday.
Sleep told Vulture: "Everyone's mouths gaped open. There was an intake of breath like they couldn't believe it. The noise got bigger and bigger.
"We did eight curtain calls. I had to bow every time and I was like, You got to bow to the prince. And she said, No, I'm not bowing to him, he's my hubby. You won't get your OBE with those comments."
However, Charles was less impressed and Morton wrote in his biography of Diana how the prince believed she was "undignified, too thin, too showy."
