Princess Catherine attended a state banquet for Oman’s Sultan Haitham bin Tariq at Windsor Castle on October 20, wearing a lemon-yellow Elie Saab cape dress and Queen Mary’s Lover’s Knot Tiara. The tiara has a history linking Queen Mary, Queen Elizabeth II and Princess Diana, and Catherine has worn it at royal occasions since 2015.
Princess Catherine wore a lemon-yellow cape dress by Elie Saab and Queen Mary’s Lover’s Knot Tiara to a state banquet at Windsor Castle on October 20, held in honor of Oman’s Sultan Haitham bin Tariq. The appearance was part of the sultan’s three-day state visit to the United Kingdom, a diplomatic occasion that brought together members of the British royal family and the visiting head of state.
The Princess of Wales’s dress came from Elie Saab’s Spring/Summer 2025 ready-to-wear collection. Harper’s Bazaar described the look as a lemon-yellow design with a woven crew neckline, an empire waist and pleated fabric. A matching bodysuit was visible beneath the semi-sheer skirt, while a light cape extended behind the dress. The outfit followed a daytime appearance in an emerald-green Alexander McQueen coatdress layered over a black blouse.
Catherine paired the gown with Queen Mary’s Lover’s Knot Tiara, a piece she has worn on multiple occasions since her first appearance in it in 2015. She also wore the Royal Victorian Order sash and star and the King Charles III Royal Family Order ribbon. Her accessories included a gold clutch, diamond chandelier earrings and a bracelet that, according to Harper’s Bazaar, had belonged to Queen Elizabeth II.
The banquet followed a welcome ceremony for Sultan Haitham, who is in Britain for a three-day state visit. Harper’s Bazaar reported that this was the first time an Omani monarch had traveled to the United Kingdom in more than 40 years. The report places Catherine’s evening appearance within the formal program of the visit, rather than presenting it as a standalone fashion event.
A Tiara With Royal History
The tiara connects Catherine’s appearance to several generations of the British royal family. Garrard made the piece for Queen Mary in 1913, according to Harper’s Bazaar. It later passed to Queen Elizabeth II, who lent it to Diana, Princess of Wales, on several occasions. Catherine’s repeated use of the tiara gives the formal outfit a historical association as well as a contemporary role in royal ceremonial dress.
The event also illustrates how clothing and insignia form part of the visual language of a state banquet. Catherine’s royal orders and sash signaled her place in the formal gathering, while the dress and jewelry made the evening’s appearance distinct from the daytime welcome ceremony. The visit’s diplomatic purpose remains the central news; the clothing details provide a documented account of how the royal family marked the occasion.

The Tiara’s Place in Royal Dress
Queen Mary’s Lover’s Knot Tiara was commissioned from jeweler Garrard in 1913. Harper’s Bazaar reports that Queen Elizabeth II later inherited it and lent it to Diana, who wore it on a number of occasions. Catherine first wore the tiara in 2015 and has since brought it out for formal royal events.
Her most recent previous use cited by Harper’s Bazaar was at a state banquet in March, when the royal family hosted Nigerian President Bola Tinubu and first lady Oluremi Tinubu. The October event for Oman’s sultan therefore continued a pattern of Catherine wearing the historic headpiece at diplomatic banquets. The source identifies the dress as a runway look from Elie Saab’s Spring/Summer 2025 collection; it does not provide further information about alterations or how the outfit was selected.
