Fashion of Catherine, Princess of Wales

The fashion of Catherine, Princess of Wales, has influenced clothing sales and consumer behaviour in the United Kingdom and beyond since her relationship with Prince William became public in 2004. She has been featured in best-dressed lists in magazines such as Vanity Fair and Tatler. Catherine's wardrobe combines pieces from the Alexander McQueen fashion house and Jenny Packham with high-street brands such as Zara, Reiss, and Hobbs.

Garments worn by Catherine are often reported to sell out shortly after, a phenomenon dubbed the "Kate effect". In 2016, Catherine appeared on the cover of British Vogue's centenary issue. Her fashion choices continue to attract global media attention.
