Princess Catherine wore a lemon-yellow Elie Saab cape dress with Queen Mary’s Lover’s Knot Tiara at an October 20 state banquet for Oman’s Sultan Haitham bin Tariq at Windsor Castle. The tiara’s history links Queen Mary, Queen Elizabeth II and Princess Diana; Catherine has worn it 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 during Sultan Haitham bin Tariq al Said’s visit to the United Kingdom. The appearance brought a historically significant royal jewel into view at a formal diplomatic event and paired it with a look from Elie Saab’s Spring/Summer 2025 ready-to-wear collection.
Harper’s Bazaar reported that the princess’s dress came from Elie Saab’s Spring/Summer 2025 collection. The lemon-yellow design had 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 publication identified it as look 56 from the collection.
Catherine completed the outfit with Queen Mary’s Lover’s Knot Tiara, diamond chandelier earrings and a bracelet that had belonged to Queen Elizabeth II. She also wore the Royal Victorian Order sash and star and the King Charles III Royal Family Order ribbon, and carried a gold clutch. The ensemble was worn for the evening banquet, following a daytime welcome ceremony for the visiting sultan.
The tiara was made by Garrard for Queen Mary in 1913 and later passed to Queen Elizabeth II, who lent it to Princess Diana on several occasions. Catherine has worn it since 2015, according to Harper’s Bazaar. The report said she most recently wore it at a state banquet for Nigerian President Bola Tinubu and First Lady Oluremi Tinubu in March.
A Familiar Tiara at a State Banquet
The outfit combined a current fashion collection with a piece of jewelry carrying a documented royal history. The tiara’s links to Queen Mary, Queen Elizabeth II and Princess Diana help explain why its appearance draws attention beyond the evening’s dress code. Catherine’s choice also reflects the use of royal jewelry at formal occasions, where clothing and insignia can serve as visible markers of the event’s ceremonial setting.
The banquet itself formed part of a diplomatic visit by Oman’s ruler. Catherine’s appearance was one element of the royal family’s welcome, rather than a separate announcement about the tiara or a change in royal policy. For readers following royal engagements and fashion, the report provides both a record of what she wore and the history attached to the headpiece.

The Tiara’s Royal History
Sultan Haitham’s visit included a welcome ceremony on October 20 and a state banquet that evening at Windsor Castle. Harper’s Bazaar reported that the visit marked the first time an Omani monarch had travelled to the United Kingdom in more than 40 years. The sultan was expected to spend three days in the country.
The Lover’s Knot Tiara was created for Queen Mary in 1913 by jewelry house Garrard. It was later held by Queen Elizabeth II, who lent it to Diana. Catherine began wearing it in 2015 and has returned to it for formal occasions. These details come from Harper’s Bazaar’s report; the source describes the tiara as one of Catherine’s favored headpieces but does not provide an official statement from the palace about the choice for this banquet.
Earlier in the day, Catherine wore an emerald-green Alexander McQueen coatdress over a black blouse, according to the same report. Her evening appearance marked a change to black-tie attire for the banquet. The available coverage identifies the dress and accessories but does not suggest that the clothes were selected to convey an official message about the diplomatic talks.
