Princess Diana was a style icon known for her unique fashion sense and bold choices. She often broke with traditional royal dress codes and instead opted for more modern, contemporary styles. Some of her most iconic looks include her off-the-shoulder cocktail dresses, oversized sweaters, and power suits. 

Diana's fashion choices were often seen as a reflection of her independent spirit and her desire to be seen as a modern, relatable royal. Her influence on fashion continues to be felt today, and many designers such as Gianni Versace have cited her as an inspiration.
