Over the weekend Kate Middleton, the Duchess of Cambridge and future Queen of England, celebrated her 40th birthday with a series of brand new royal portraits. Shot by Paolo Roversi for the National Portrait Gallery, the series of images showed the Duchess wearing three different gowns by Alexander McQueen (who she also wore for her wedding to Price William), looking absolutely radiant as she enters the next decade of her life.

The royal has always been a woman decorated for not only her philanthropic efforts but also her penchant for style, expertly weaving monarch fashion traditions with modern modern sensibilities — and looking every inch a future monarch in the process. Not to mention her iconic bouncy blow dry, and natural but always glamorous makeup aesthetic.

So in honour of her birthday, we’re rounding up 15 of the Duchess’ most memorable beauty looks, from crown jewel-adorned up-do’s to her enviable natural waves. Keep scrolling to discover.
