The Princess of Wales is back in the fashion spotlight

The fashion crowd in London is generally known for keeping cool. But on Tuesday, the editors and designers at a ceremony for one of the industry’s most prestigious local awards became palpably excited when Catherine, Princess of Wales, emerged to present this year’s Queen Elizabeth II Award for Design to Patrick McDowell, 29, a Liverpool-born designer.

Dressed in an olive Victoria Beckham suit and a white silk pussy-bow blouse, Catherine walked with Mr. McDowell among mannequins and models wearing the designer’s looks inside 180 the Strand, the Central London building where the event took place. It was the second time the princess had presented the award, which was created by the British Fashion Council and the British royal family in 2018 to recognize the role London’s fashion industry “plays in society and diplomacy.”

The princess did not give public comments at the ceremony, but Mr. McDowell said that their private conversation touched on topics including a shared appreciation for craftsmanship and the designer’s efforts to make collections in Britain and offer customers the option to repair or rework old garments.

Mr. McDowell added that, as Catherine toured the clothes on display, she took interest in a tailored sleeveless jacket called “the Wales jacket.”

“She said, ‘Why would you call it that?’ with a big smile,” Mr. McDowell said. “What a moment, to be sharing jokes with our future queen.”

Catherine’s appearance at the event came as she has been stepping up the pace and profile of her public engagements after her cancer diagnosis and treatment last year. In January, she said her cancer was in remission; about a month later, the Sunday Times of London published an article that suggested that Kensington Palace would no longer be disclosing any details of her outfits to the news media.

During the awards ceremony, the princess also met with other young designers who were on hand to showcase their wares, including Conner Ives, an American working in London whose “Protect the Dolls’ T-shirt have spread widely on social media in recent weeks. On Tuesday, Mr. Ives was announced as the 2025 winner of the British Fashion Council/Vogue Designer Fashion Fund award, which came with a grant and an industry mentorship.

In past years, the Queen Elizabeth II Award for Design went to designers including Richard Quinn, S.S. Daley and Priya Ahluwalia. It has been presented in the past by other senior royals, including Queen Elizabeth II, King Charles III and Princess Anne.

Mr. McDowell, whose namesake brand was introduced in 2018, is known for offering made-to-order evening and occasion wear designed in London using recycled textiles and new sustainable materials like sequins made of cellulose. Lady Gaga, Sarah Jessica Parker and Keira Knightley are among the label’s notable fans.

Winning the Queen Elizabeth II Award was “a wonderful pat on the back that provides a game-changing stamp of approval,” Mr. McDowell said, as well as an “acknowledgment that working in a circular way is a way forward.”

“I’d love to make a piece for her,” Mr. McDowell added, referring to Catherine. “It would be a dream come true.”
