Since marrying into the Royal Family in 2011, Catherine has captured the fashion world's attention with her classic style and silhouettes - and that hair!
The want to emulate her looks has seen many companies benefit from the 'Kate-effect', with items the Duchess has worn selling out within minutes, or becoming an iconic piece within the brand's collection.
Her favourite brands include Alexander McQueen, LK Bennett, Zara, Hobbs, Jenny Packham, Gianvito Rossi, Topshop and Catherine Walker. She mixes high-end with high-street, championing British brands.
Replicate Royalty is here to tell you what she has been wearing, where you can buy it, or if there is a cheaper 'replikate' available to copy Kate's style.
