Kate has become a true style icon since she became a princess, with her professional and elegant looks stealing the show.
But it's not just about looking good, she also carries out royal duties and campaigns for children's development.
Despite her love for formal outfits, Kate now prefers polka-dot tea dresses to trouser suits.
She's not just a fashionista, but also a diplomat, as she chooses clothing colors to honor national flags, flowers or scenery.
As King Charles is set to ascend the throne in May, people expect Kate to adopt a more conservative style.
