Behind every great style icon is another great style icon. We wouldn't have our Olivia Palermos and Victoria Beckhams without Audrey Hepburn. Where would the Kardashians and Jenners be without Marilyn Monroe? And we would argue Kate Middleton might have a touch less glamour if she weren't following in the formidable footsteps of Princess Diana. Hey, you don't get a Tod's bag named after you for nothing!
To mark what would have been the Princess of Wales's 57th birthday, we're looking back at her most memorable fashion moments — from the diamonds to the wellies — to celebrate the bold, showstopping, and unapologetic choices that made her the people's princess. While they all may be from another decade, much like Diana herself, each look is totally timeless.
