'I literally had one long dress, one silk shirt, one smart pair of shoes and that was it' - so Princess Diana said of the day she and Prince Charles got engaged. Sixteen years later, Diana would die, no longer the girl with one dress, but a global fashion icon who had raised more than GBP2 million for charity by selling 79 of her dresses at Christie's auction house in New York.

This chic and stylish book opens Diana's wardrobe to the world. From the Regamus debutante's dress Diana wore at a ball at Althorp, her family estate, to her infamous Christina Stambolian 'Revenge' dress, which she wore on the night Prince Charles publicly admitted his adultery with Camilla Parker Bowles, each iconic moment is captured in these pages.

Claudia Joseph chronicles Diana's style evolution from the days she shopped with her mother for her wedding trousseau at Harrods, to her discovery of her wedding dress designers, the Emanuels, and her relationship with Vogue fashion director Anna Harvey, who introduced her to designers such as Catherine Walker, Jacques Azagury and Versace. She looks at the designers who shaped Diana's image and tracks down her most symbolic dresses to museums around the world.
