They wowed the crowds with complimentary looks!

Princess Kate and Sophie, Duchess of Edinburgh were cheered by royal fans as they arrived at Windsor Castle for the annual Garter Day procession and service on Monday (June 16) afternoon.

However, the Princess of Wales and Prince Edward’s wife were not attired in the distinctive ceremonial robes worn by members of the Order of the Garter for the occasion, including by their husbands.

Instead, Kate, 43, and Sophie, 60, stood out in matching outfits that evidenced their strong bond, which has been previously likened to that of sisters.

What Princess Kate and Sophie wore for Garter Day 2025

According to reports, Princess Kate wore an ensemble by designer Self Portrait.

It is believed the cream chiffon midi dress and blazer bodice may be the same combo she wore for May’s VE Day concert.

However, for Garter Day, she accessorised her look with hat by Sean Barrett. Furthermore, it is believed Princess Kate was wearing a pair of vintage pearl earrings.

Sophie, meanwhile, also looked stunning in a pale pink wrap-style dress, also with matching hat. And as they arrived for Monday’s event – with the Order of Garter created nearly 700 years ago by King Edward III – both Kate and Sophie were applauded by impressed, devoted supporters.

In a video shared to X, Sophie and Kate were seen arriving at St George’s Chapel at Windsor Castle together. Applause and cheers were heard.

Do Kate and Sophie get along?

According to reports, the bond between Princess Kate and Duchess Sophie has always been strong – and may have grown even closer over the last year.

Royal author Ingrid Seward believes the pair are “incredibly kind girls”, who are almost like siblings.

She told HELLO! in November 2024: “They have a sisterly bond and Sophie is like the older sister Kate never had.”

The commentator went on: “They are both protective of their children. Sophie has had a young family. So she knows what it’s like trying to protect them while being in the royal world.”

Furthermore, correspondents have also suggested Sophie’s support has been increasingly clear as Kate has returned to public duties following chemotherapy.

The duchess stood alongside Kate for 2024’s Remembrance Sunday service – and even placed a supportive hand on Kate’s back. And it was also noted in December how Sophie sat next to Kate for her annual Together at Christmas concert at Westminster Abbey.

Additionally, biographer Claudia Joseph reflected to The Sun in the weeks following Kate’s cancer announcement how Sophie may be able to empathise about Kate’s journey into the royal family.

She said at the time: “[Sophie] is 17 years older than Kate and has seen and done it all before.”

Sophie is a true confidante and sounding board.

Ms Joseph went on about Kate: “She has found that Sophie is a true confidante and sounding board. And they have developed a mutual respect and an unbreakable bond.”
