Princess Diana, a fashion icon beloved by many, is the focus of a new exhibition shedding light on how she navigated the strict dress codes of royalty. Scheduled to debut on March 13 at Kensington Palace and running through Nov. 30, 2025, the Dress Code exhibition features 34 meticulously chosen outfits, including three worn by Diana, alongside two dresses from the late Princess Margaret. This exhibit offers a glimpse into Diana’s style evolution, from a humble country girl to a globally recognised fashion influencer.

One of the highlighted pieces in the showcase is a stunning red Bruce Oldfield gown that Diana donned during a state visit to Saudi Arabia in 1987. This gown is juxtaposed with a green tweed hacking jacket associated with her country retreat, Althorp House, illustrating the contrast in her wardrobe as she transitioned into a fashion icon on the world stage. According to Caterina Berni, a senior interpretations manager at Historic Royal Palaces, by 1987, Diana had mastered the art of understanding and adhering to royal dress codes.

Another notable ensemble at the exhibition is Diana’s red Jasper Conran suit worn during the christening of a cruise ship in 1984. Additionally, a Catherine Walker green silk velvet tuxedo-style dress, which Diana wore to private family gatherings before unveiling it to the public in 1997 through a charity auction, showcases her diverse fashion choices and philanthropic spirit. The exhibit also includes matching floral dresses worn by a young Queen Elizabeth II and Princess Margaret in 1936, reflecting the royal family’s thriftiness and providing insights into their early years.
The Dress Code exhibition further highlights Princess Margaret’s style journey with pieces like a 1978 Thea Porter evening ensemble and a 1980 Jose Pitoy Moreno green embroidered gown. These outfits symbolise Margaret’s foray into London’s creative scene and her emergence as a style icon, as described by Berni. Curated by Matthew Storey, the exhibition theme of dress codes aims to explore the intricate customs of royal attire and how fashion can challenge boundaries and evolve over time.
Moreover, the exhibition delves into uniforms worn by postilion riders and former members of the Royal Yacht Britannia, emphasizing the evolution of fashion rules and their significance in royal circles. A standout element of the exhibition is the involvement of young participants aged 14-17, who served as Young Producers and even staged a fashion show at Kensington Palace in February. Their creations were inspired by the royal attire displayed, showcasing a blend of tradition and modern interpretation.
In conclusion, the Dress Code exhibition at Kensington Palace offers a fascinating insight into Princess Diana’s sartorial choices and the significance of adhering to dress codes within royal circles. Through a curated collection of outfits and a thematic exploration of fashion rules, the exhibition celebrates Diana’s enduring influence on style and her ability to transcend fashion boundaries with grace and elegance.
It’s evident that Princess Diana’s impact on fashion and style continues to inspire generations, and this exhibition serves as a poignant tribute to her timeless elegance and fashion legacy.
