Kate Middleton, Queen Camilla and Brigitte Macron made a unified sartorial statement with their attire at a state banquet on Tuesday held at Windsor Castle in Windsor, England. The Princess of Wales opted for a design by Givenchy, with Queen Camilla favoring one of her go-to designers, Fiona Clare, and Macron styled a custom royal blue cape gown by Louis Vuitton for the special occasion.

Middleton’s bespoke Givenchy gown was designed by Sarah Burton, who also designed the British royal family member’s ornate lace wedding gown worn to her Westminster nuptials to Prince William in April 2011.

The Princess of Wales’ gown featured flowing chiffon fabric, with a sleeveless design, cinched waist for added silhouette definition and an elegant skirt. The gown also featured a cape element over the British royal’s shoulders. Middleton carried the Lily of the Valley Embroidered Evening Clutch courtesy of Givenchy.

As for finishing touches and further accessories, she wore a pair of burgundy velvet pumps by Jimmy Choo and the Queen Mary’s Lover’s Knot Tiara and the Greville Chandelier Earrings (both from Queen Elizabeth II’s personal collection). The tiara is estimated to be worth roughly $1.3 million, according to the experts at Steven Stone in London. The tiara was designed by Queen Mary and then passed on to her granddaughter, Queen Elizabeth II. Middleton also wore Princess Diana’s three-strand pearl bracelet.

Queen Camilla wore a Fiona Clare ivory silk gown with embroidery on the front of the skirt and at the hemline and sleeves. She also carried the ‘Bella’ clutch in silver by Launer London.

As for her jewels, Queen Camilla wore the late Queen Elizabeth II’s Belgian Sapphire Tiara. She coordinated the tiara with Queen Elizabeth II’s matching sapphire and diamond cluster line necklace as well as the sapphire earrings. The tiara is estimated to be worth $6.79 million, while the necklace is valued at $5.4 million, and the earrings are estimated to be worth roughly $407,000, according to the experts at Steven Stone in London.

Brigitte Macron wore a deep blue silk crepe column gown by Louis Vuitton that featured a cape effect similar to that of Middleton’s dress. The shoulders of the dress also included hand-embroidered black and silver jewel embellishments.

Macron accessorized her attire with jewels courtesy of the French luxury fashion house as well. The red, white and blue colorscape of Middleton, Queen Camilla and Macron’s attire seemingly referenced the colors of both the French flag and the flag of the U.K., also known as the Union Jack, creating an overall unified statement.

French President Emmanuel Macron began his three-day state visit to the U.K. on Monday, marking the first visit by a European Union leader since the U.K.’s departure from the European Union, commonly referred to as Brexit. The visit underscores efforts to renew ties between the two countries amid ongoing challenges such as migration across the English Channel and the war in Ukraine.
