Princess Iman of Jordan is a timeless princess bride!

The 26-year-old daughter of Queen Rania and King Abdullah II of Jordan married Jameel Alexander Thermiotis in a stunning royal wedding in Amman, Jordan on Sunday. Princess Iman glowed in a white wedding dress by Dior with a high illusion neckline and long sleeves cuffed with the same lace. The pattern matched the embroidery on her sweeping veil, which was tucked into her tiara.

The headpiece was somewhat of a surprise, as speculation swirled that Iman would wear her mother's Diamond Tiara after Queen Rania, 52, posted a photo of her daughter in the headpiece last week.

The mother of the bride also wore Dior for the wedding, beaming in a pleated beige gown with a high neckline and elbow-length sleeves. While the bride's gown was bespoke, Harper's Bazaar Arabia reports that Rania's dress comes from the Autumn 2022 Couture collection.

"Just married !! All my deepest congratulations to the bride and the groom and long life to the Happy married couple👰‍♀️🤵‍♂️♥️," Dior Couture PR manager Mathilde Favier wrote on Instagram, confirming that the gowns were by the French fashion house.

Completing the look, Princess Iman wore dangling diamond earrings with her hair swept back into a low chignon with loose face-framing pieces.

Thermiotis, 28, was classic in a three-piece suit with a tie. Princess Iman walked down the aisle with her elder brother, Crown Prince Hussein, and exchanged rings with her groom during the intimate indoor ceremony, which brought the outdoors in with white spring branches and floor-to-ceiling glass windows.

"A day unlike any other. Thank you all for sharing in our joy," Queen Rania wrote on Instagram, posting photos from the royal wedding.
