Kate Middleton has recently received a royal honour that hasn’t been granted to a Princess of Wales in more than 100 years—a responsibility last held by Queen Elizabeth II’s grandmother, Princess Mary of Teck.

A Title with Historic Roots

After the passing of Queen Elizabeth II in 2022, Kate, 43, assumed the title of Princess of Wales alongside her husband Prince William, now the Prince of Wales. Before Kate, the title had not been officially used since 1997, the year of Princess Diana’s tragic death in Paris. Although Diana famously held the title, she was never given this particular distinction during her lifetime.

A Role Not Seen Since Queen Mary

This past week, Kate was granted a significant royal duty—one that was last held by Queen Mary (formerly Princess Mary of Teck): the power to issue Royal Warrants. These warrants are formal recognitions granted by the monarchy, allowing businesses to display the Royal Arms on their products as a mark of official patronage.

Endorsing British Craftsmanship

William’s private secretary, Ian Patrick, shared with HELLO! magazine, “Their Royal Highnesses are delighted to be able to recognize and celebrate British industry, creativity, and skills through the granting of Warrants.” These warrants are typically awarded for a five-year period and signal that the recipient has provided goods or services directly to a royal household.

By next year, Kate and William will officially begin selecting the companies they wish to support. This not only honors those businesses, but also gives them permission to display the royal coat of arms on their packaging—a powerful symbol of royal endorsement.

The ‘Kate Middleton Effect’ in Action

Kate’s influence, especially in the fashion world, has long been noted. The term “Kate Middleton effect” refers to the economic boost her style choices bring to the fashion industry. Since her marriage to Prince William in 2010, it’s estimated that her fashion impact contributes around £1 million annually to the UK economy.

According to HELLO!, “The princess’s decision to back a certain brand or firm will likely generate a huge amount of business and publicity for them.” With the new warrant-issuing power, that influence is expected to grow even further.

Likely Recipients of Royal Endorsement

Among the designers and brands that could receive this prestigious recognition are fashion houses such as Catherine Walker, Jenny Packham, Alexander McQueen, and Erdem—labels that Kate frequently wears. Accessories brands like Kiki McDonough, Robinson Pelham, and Catherine Zoraida are also likely candidates for royal approval.

Kate’s new privilege not only revives a royal tradition that has been dormant for a century but also allows her to play a key role in supporting and elevating British businesses—much like her predecessors, but with a distinctly modern touch.
