Kate Middleton breaks her golden rule at Peter Phillips’ wedding: this never-before-seen dress by a top designer is causing a sensation
On June 6, 2026, the wedding of Peter Phillips and Harriet Sperling in Gloucestershire brought together much of the Windsor clan. Among the guests, Kate Middleton, as always, drew the attention of royal watchers. Yet on that day, the Princess of Wales made a fashion choice that surprised more than a few royal experts.
An unwritten rule that has been followed for years
For a long time, the Princess of Wales has followed a discreet rule when attending weddings. Her principle is simple: to reuse outfits she has already worn, so as never to upstage the bride and groom. This habit has thus become a sign of respect for the couples being celebrated.
In 2018, at the wedding of Prince Harry and Meghan Markle, she wore an Alexander McQueen coat dress that she had previously been seen wearing. Similarly, in 2023, for the wedding of Crown Prince Hussein of Jordan and Princess Rajwa, she wore a powder-pink Elie Saab gown that she had worn several years earlier at her sister Pippa Middleton’s wedding.
This consistency in her choice of attire at royal ceremonies has thus become a true signature. Royal observers view it as a thoughtful gesture toward the bride and groom of the day.
Peter Phillips’ Wedding: A Notable Exception
To attendthe service at All Saints Church in Kemble, however, Kate Middleton made an unusual choice. She opted for a cream-colored, textured midi dress by Roland Mouret, which Hello! Magazine noted was a completely new addition to her wardrobe.
This outfit stands out for its structured collar, front buttons, belted waist, and pleated skirt. Thus, for the first time at a royal wedding, the princess wore an outfit that had never been seen before.
“Her Royal Highness the Princess of Wales was spotted last week wearing our iconic Malory pumps, a pair she has owned and worn for over ten years.”
Accessories that complement her signature style
Although the dress was a new addition to her wardrobe, the Princess of Wales remained loyal to several pieces she has long cherished. She once again wore her Rupert Sanderson Malory pumps, which she has worn on numerous occasions over the years. The brand even paid tribute to her loyalty on Instagram.
In addition, the future queen wore a new straw hat by Jane Taylor London, adorned with a satin bow that matched her dress. She also carried a woven clutch from the Australian brand Forever New, as well as pink stone earrings by Kiki McDonough, which she had previously worn at Pippa Middleton’s wedding in 2017.

The Rupert Sanderson brand also took to Instagram to highlight the princess’s devotion: “This is what makes Rupert Sanderson proud as a shoemaker: creating a perfectly balanced piece that stands the test of time, both in terms of craftsmanship and style. ” A discreet tribute to a loyalty that is rare in royal fashion circles.
On Prince William’s arm, the princess exuded a blend of renewed elegance and confident continuity. The couple’s children—George, Charlotte, and Louis—were, however, absent from the ceremony that day.
A quiet tribute to Princess Diana
Beyond fashion, it was a powerful symbolic gesture that caught everyone’s attention. Kate Middleton chose to wear the three-strand pearl bracelet that had belonged to Princess Diana. This piece was created by jeweler Nigel Milne to support the charity Birthright, of which Lady Diana was the patron.
This choice is therefore a subtle tribute to her late mother-in-law. Through this gesture, the Princess of Wales forges a quiet link between the royal family’s past and present.
The Windsor family gathered to celebrate Peter Phillips
Beyond the princess’s style, the ceremony on June 6, 2026, brought together many members of the royal family. King Charles III and Queen Camilla were among the distinguished guests. Princess Anne, the groom’s mother, was naturally in attendance to celebrate her son’s second wedding.
Zara Tindall and her husband Mike Tindall, as well as Princesses Beatrice and Eugenie, accompanied by their respective husbands, Edoardo Mapelli Mozzi and Jack Brooksbank, were also in attendance. For their part, Prince Edward and his wife Sophie graced this beautiful family gathering with their presence.
Samuel Chatto, Princess Margaret’s grandson, and his girlfriend Eleanor Ekserdjian had also been invited to the party. The bride, Harriet Sperling, wore a stunning lace gown by Emilia Wickstead, featuring a 3.5-meter-long train. She also wore a pearl and diamond tiara on loan from Pragnell, featuring Edwardian and Art Deco styles, with royal connections dating back to the coronation of King George VI.
Georgina Sperling (13), the bride’s daughter, along with Savannah (15) and Isla Phillips (14), the groom’s daughters, served as bridesmaids. It was a day of celebration, then, during which the Princess of Wales managed to combine unparalleled elegance with gestures full of meaning.
