The Princess of Wales made a striking return to the royal spotlight last night, joining Prince William for a white-tie banquet at Windsor Castle held in honour of French President Emmanuel Macron and First Lady Brigitte Macron.
The high-profile state dinner marked Kate’s first formal royal banquet appearance since November 2023 — and her first since publicly announcing her cancer diagnosis earlier this year. In March, the Princess revealed she had been undergoing preventative chemotherapy. She later shared in June that her treatment had ended and she was in remission.
But it wasn’t just her radiant return that had everyone talking — it was what she wore.
Kate arrived in a deep burgundy silk creponne gown, custom-designed by Sarah Burton for Givenchy. The dress featured a gathered silhouette with elegant cape-back detailing — a dramatic and regal departure from her usual preference for blues at state functions.
She paired the look with several royal orders and honours, including the GCVO sash, the Royal Family Orders of both King Charles III and the late Queen Elizabeth II, and the Rosette of Grand Officier de l’ordre national du Mérite — a nod to the evening’s French guests.
Yet, it was her tiara that drew the most attention.
Kate wore the Cambridge Lover’s Knot tiara — one of the most iconic pieces from the late Princess Diana’s collection. The headpiece once belonged to William’s mother and has become closely associated with her image during the height of her royal years. For many viewers, it was a quiet, elegant tribute from Kate to the woman who would have been her mother-in-law.
Social media lit up with admiration for the Princess of Wales, with fans commenting not just on her beauty, but the symbolism behind her look.
“Hands down the most beautiful and elegant mother, woman in the world — Diana would be so proud of you!” one person wrote.
Another added, “My favourite tiara, worn to perfection.”
A third summed up the sentiment simply: “A red dress and Diana’s favourite tiara — yes!”
Kate’s appearance was more than a fashion moment. For many, it symbolised strength, grace, and a seamless bridge between royal generations.
