It isn't every day that you see a European royal donning a dazzling tiara, never mind two together. But it was in June 2023 when Queen Mary and Princess Kate flew to Jordan for the wedding of Crown Prince Hussein and Princess Rajwa that royal fans delighted in just that.
Princess Kate and then-Princess Mary of Denmark were seen at the evening do in a photo that has gone largely unnoticed, where royal fans can see the elegant royals in a rare twinning tiara moment.
The Princess of Wales attended the reception at the Al Husseiniya Palace alongside her husband Prince William looking poised as ever in her beautiful Jenny Packham floor-length gown featuring a round neckline and long sleeves.
Kate swept her cascading brunette locks away from her face to show off her breathtaking Cambridge Lover's Knot tiara. The dazzling headpiece was made for Queen Mary in the early 20th century by the House of Garrard using pearls and diamonds in her family's collection.
The mother of three also wore the sparkling Greville Chandelier Earrings which had belonged to the late Queen Elizabeth.
Meanwhile, Crown Princess Mary shone in an equally beautiful tiara moment. The Australian-born Danish royal wowed in the Edwardian Tiara. The future Queen first wore the diamond headpiece in April 2015 at a concert celebrating her mother-in-law Queen Margrethe's 75th birthday in Aarhus.
She paired her gorgeous tiara with a chic updo to accentuate the beauty of her floor-length pale blue gown which featured a one-shouldered neckline with gold embroidery over the bodice and a floaty skirt.
Kate and Mary were seen chatting at the reception, having attended the formal Islamic ceremony earlier in the day at Zahran Palace. Princess Kate arrived in a breathtaking pale blush pink floor-length gown made by Elie Saab - the Lebanese fashion designer who made Princess Rajwa's first bridal gown of the day.
The Princess of Wales's gown featured a high neckline, embellished sleeves, and a floaty skirt. She carried an understated envelope clutch and wore her hair in uniform Hollywood curls to show off her statement earrings.
Princess Mary matched Kate's wedding guest elegance in the 'Agnes' gown by Erdem - a white floor-length gown covered in a blue floral print. The gown featured a cinched waistline and was paired with the timeless Manolo Blahnik 'Hangisi' heels.
The bride looked straight from a fairytale in not one, but two gowns. Her first was a more slim-fit number with a high neck and long sleeves. The other, which was made by Dolce and Gabbana, was a more traditional ballgown with statement flowers covering the entire garment.
