When it comes to royal style, few people take the crown quite like the Princess of Wales. Since joining the royal family in 2011, Catherine has cemented herself as a fashion icon, regularly landing on best-dressed lists.
"Clothes never seem to wear her – she has an innate elegance that allows even the most elaborate outfits to feel approachable. This, paired with her acute understanding of how to dress for her role, makes her a true modern style icon," British fashion designer Amanda Wakeley OBE previously told HELLO!.
Whether she's in a coatdress, a tailored pantsuit or a glittering gown and tiara, the Princess has shown time and time again why she's the royal family's reigning style star.
"An impeccable royal outfit seamlessly marries elegance with purpose," Amanda said. "It has to convey respect for the occasion, cultural awareness when necessary, and must be timeless. Often, it's all about the details – subtle tailoring, quality fabrics and accessories that amplify rather than overwhelm."
The result? Catherine's outfits make headlines and have created a phenomenon known as the "Kate effect."

"The Princess of Wales spawned the Kate effect from the moment she became engaged to Prince William," HELLO!'s online royal correspondent Danielle Stacey has said. "And while she has access to some of the best designers and fashion houses, her penchant for mixing high-end with the high street has made her a relatable style icon."
From royal engagements to state visits and royal tours, here are some of the Princess' best fashion moments.

The Princess wore a dress fit for a future Queen Consort for her grand debut as a member of the royal family. Catherine married Prince William in a gown designed by Sarah Burton for Alexander McQueen. According to the palace, the Princess chose the "British brand Alexander McQueen for the beauty of its craftsmanship and its respect for traditional workmanship and the technical construction of clothing" and "wished for her dress to combine tradition and modernity with the artistic vision that characterises Alexander McQueen's work."
Elizabeth Holmes, author of HRH: So Many Thoughts on Royal Style, has described the dress to HELLO! as "a classic that let [Catherine] shine through."
