Princess Catherine wore a lemon-yellow cape dress from Elie Saab’s Spring/Summer 2025 ready-to-wear collection and Queen Mary’s Lover’s Knot Tiara at a state banquet for Oman’s Sultan Haitham bin Tariq. The banquet was part of the sultan’s three-day state visit to the United Kingdom, which the source report says is the first visit by an Omani monarch in more than 40 years.

Princess Catherine wore a lemon-yellow cape dress by Elie Saab and Queen Mary’s Lover’s Knot Tiara at a state banquet for Oman’s Sultan Haitham bin Tariq at Windsor Castle on October 20. The evening event formed part of the sultan’s three-day state visit to the United Kingdom, a diplomatic visit that the source report describes as the first by an Omani monarch in more than 40 years.

The Princess of Wales’s dress came from Elie Saab’s Spring/Summer 2025 ready-to-wear collection. Harper’s Bazaar described it 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, trailing cape completed the look. The outlet identified the design as look 56 from the collection.

Catherine paired the dress with Queen Mary’s Lover’s Knot Tiara, a headpiece she has worn on several occasions. Harper’s Bazaar reported that she first wore it in 2015 and most recently wore it at a state banquet in March for Nigerian President Bola Tinubu and First Lady Oluremi Tinubu. The tiara was made by Garrard for Queen Mary in 1913, later passed to Queen Elizabeth II, and was lent by her to Princess Diana.

For the banquet, Catherine also wore the Royal Victorian Order sash and star and the King Charles III Royal Family Order ribbon. Her accessories included diamond chandelier earrings and a bracelet that had belonged to Queen Elizabeth, along with a gold clutch. Earlier in the day, she had worn an emerald-green Alexander McQueen coatdress over a black blouse for the sultan’s welcome ceremony, according to the report.

The developmentPrincess Catherine wore an Elie Saab cape dress and the Lover’s Knot Tiara to the state banquet welcoming Oman’s sultan at Windsor Castle.

A Formal Look for Oman’s State Visit

The outfit was worn at a formal diplomatic occasion, not simply a private or public fashion appearance. The banquet was part of the British royal family’s welcome for Sultan Haitham bin Tariq, whose visit included a welcome ceremony at Windsor Castle. The clothing and ceremonial insignia formed part of the evening’s formal presentation, while the event itself underscored the diplomatic relationship between the United Kingdom and Oman.

The tiara also carries a documented royal history. Its connections to Queen Mary, Queen Elizabeth II and Princess Diana give it significance beyond its use as an accessory. Catherine’s choice returns a familiar heirloom to a high-profile state occasion, though the source report does not attribute a specific diplomatic message or personal intention to her selection.

The Tiara’s Royal History

Garrard made the Lover’s Knot Tiara for Queen Mary in 1913. It later entered Queen Elizabeth II’s collection, and she lent it to the late Princess Diana on several occasions. Catherine has worn the piece since 2015, making it a recurring choice for formal events. The report notes that she wore it at the March state banquet for Nigeria’s president and first lady.

The October 20 banquet followed a welcome ceremony earlier that day at Windsor Castle. Sultan Haitham was due to spend three days in the United Kingdom. Harper’s Bazaar characterized the visit as the first time an Omani monarch had traveled to the UK in more than 40 years; the report does not provide further detail about the previous visit or the full schedule of this one.

Details Beyond the Banquet

The available report identifies the dress, tiara and several accessories, but it does not provide a statement from Catherine or the royal household explaining why she chose them for this event. Any claim that the color or jewels were intended to convey a particular message would go beyond the information supplied.

The source also gives limited detail about the rest of the sultan’s visit, including its full itinerary and the subjects discussed during official meetings. The reported “more than 40 years” comparison is presented by Harper’s Bazaar; no exact date for the previous visit is included in the material provided.

The Visit Continues in Britain

Sultan Haitham’s state visit was scheduled to continue over the three days following his welcome at Windsor Castle. The supplied report does not specify the remaining events or say whether further public appearances by Catherine and Prince William were planned. Further details about the visit’s program and official outcomes would clarify what followed the banquet.

For now, the confirmed development is the royal family’s welcome and the state banquet on October 20, where Catherine wore the Elie Saab dress with the historic Lover’s Knot Tiara.
