The Princess of Wales has cemented her status as one of the world's most fashion-forward royals.

Alongside her gracious and modest dress code, she is committed to modernity and championing all kinds of fashion through her varied style agenda - from British designer labels to affordable high street heroes. And whether she’s nailing high-low pairings or strategically coordinating her accessories, her styling hacks are a lesson to us all. 

It’s been almost 13 years since Kate Middleton became a royal, and just over a year since she became a Princess after the death of the late Queen Elizabeth II.  "In her new role as Princess, Kate's style has evolved from conservative elegance to embracing bolder, more contemporary fashion choices while maintaining her signature royal grace," explains Hello! Fashion's digital editor Natalie Salmon.

As she celebrates her 42nd birthday today -  we take a look at her most memorable looks since becoming the Princess of Wales.
