LONDON With great power comes great fashion responsibility, a cue that every royal understands whenever they step out in public, whether interested in fashion or not.

Kate Middleton is a master of this and she often doesn’t need to say anything: her clothes do the talking.

Throughout the years, Catherine, Princess of Wales’ staple silhouette of structured shoulders, body-hugging bodices and cinched waists have had some reconstruction, just like her role within the British royal family.

Since the passing of Queen Elizabeth II in September, the duties and responsibilities of the Waleses have increased.

In 2023, Middleton’s hemlines became longer and her support for British designers got stronger.

“If you look back at their trajectory as a couple, for a very long time they were seen as very relatable, very down to earth and quite casual. I think what we’ve seen a little bit more of in recent months is them looking much more serious,” Bethan Holt, author of “The Queen: 70 Years of Majestic Style” and “The Duchess of Cambridge: A Decade of Modern Royal Style,” told WWD ahead of King Charles III’s coronation.

BOSTON, MASSACHUSETTS - DECEMBER 01: Prince William, Prince of Wales and Catherine, Princess of Wales visit Greentown Labs, North America’s largest clean-tech incubator, on December 01, 2022 in Boston, Massachusetts. The Prince and Princess of Wales are visiting the coastal city of Boston to attend the second annual Earthshot Prize Awards Ceremony, an event which celebrates those whose work is helping to repair the planet. During their trip, which will last for three days, the royal couple will learn about the environmental challenges Boston faces as well as meeting those who are combating the effects of climate change in the area.

On the world stage, her support means that eyes are always on designers coming out of Britain, from Stella McCartney, Emilia Wickstead to Self-Portrait.

According to reports from WeArisma, an influence analytics company, Kate Middleton’s appearance was one of the most influential moments during the coronation. The Alexander McQueen gown she wore had an engagement value of $349,700 based on an image from Time magazine’s Instagram.
