Princess Catherine wore a lemon-yellow Elie Saab cape dress with 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 tiara has a history spanning Queen Mary, Queen Elizabeth II and Princess Diana, and has been part of Kate’s formal wardrobe since 2015.
Princess Catherine wore Queen Mary’s Lover’s Knot Tiara with a lemon-yellow Elie Saab cape dress at a state banquet for Sultan Haitham bin Tariq of Oman at Windsor Castle on October 20. The banquet was part of the sultan’s three-day state visit to the United Kingdom, the first visit by an Omani monarch in more than 40 years, according to Harper’s Bazaar.
The Princess of Wales chose a design from Elie Saab’s Spring/Summer 2025 ready-to-wear collection. The dress featured a woven crew neckline, an empire waist and pleated fabric, with a matching bodysuit visible beneath its semi-sheer skirt. A light, trailing cape completed the look. Harper’s Bazaar identified it as Look 56 from the collection.
For the formal occasion, Catherine paired the dress with the Lover’s Knot Tiara, a headpiece she has worn on multiple occasions since first wearing it in 2015. The tiara was made by Garrard for Queen Mary in 1913 and later passed to Queen Elizabeth II, who lent it to Diana, Princess of Wales. Catherine also wore a Royal Victorian Order sash and star and the King Charles III Royal Family Order ribbon.
Her other accessories included a gold clutch, diamond chandelier earrings and a bracelet. Harper’s Bazaar reported that the earrings and bracelet had belonged to Queen Elizabeth II. Earlier on October 20, Catherine had attended the sultan’s welcome ceremony in an emerald-green Alexander McQueen coatdress over a black blouse before changing for the evening banquet.
A Tiara With Royal History
The appearance brought together a contemporary fashion choice and a piece of jewelry associated with several generations of the British royal family. Queen Mary’s Lover’s Knot Tiara is notable for its documented history: it was made in 1913, later belonged to Queen Elizabeth II and was lent to Diana. Catherine’s repeated use of it connects her formal appearances with that earlier royal record, without changing the tiara’s ownership history.
The occasion also had diplomatic significance beyond the clothing. The banquet formed part of a state visit by Oman’s sultan, whose trip was described by Harper’s Bazaar as the first visit by an Omani monarch to the United Kingdom in more than four decades. The royal family’s participation and the formal evening event were elements of the visit’s public program.
For readers following royal fashion, the outfit offers a specific example of how a public appearance combines designer clothing, ceremonial dress and inherited or historically significant jewelry. The available report identifies the dress and accessories, but does not provide information about the choice’s symbolism or the designers’ involvement in selecting the outfit.

The Tiara’s Path Through Three Generations
Garrard made the Lover’s Knot Tiara for Queen Mary in 1913. It subsequently entered Queen Elizabeth II’s collection, and she lent it to Diana, Princess of Wales, for use on several occasions. The report says Catherine first wore it in 2015 and has since returned to it for formal events.
Her most recent prior use cited by Harper’s Bazaar was at a state banquet in March, when the royal family welcomed Nigerian President Bola Tinubu and first lady Oluremi Tinubu. That earlier appearance shows the tiara’s continuing place in Catherine’s formal wardrobe; the source does not list every occasion on which she has worn it.
The Oman banquet followed a welcome ceremony at Windsor Castle on the morning of October 20. The sultan was scheduled to spend three days in the United Kingdom. The report links the visit to the banquet but does not give further details about the diplomatic agenda or the meetings planned during the trip.
