Jordan's Queen Rania greeted guests in a glamorous embroidered Dior gown at the wedding ceremony of her son, Crown Prince Hussein, and Princess Rajwa at Zahran Palace on Thursday.

The sleek dress featured intricate flower detailing on the arm, collar and back. She paired the look with a matching clutch bag.

Princess Muna Al Hussein, King Abdullah II's mother, wore a purple gown as she arrived with her entourage and greeted the parents of the groom.

Jordan's Princess Iman, who married Jameel Thermiotis on March 12, wore a stone-coloured dress with bulbous arm detailing from Ashi Studio, the Beirut label founded by Saudi designer Mohammed Ashi.

Her sister Princess Salma wore a blue draped Stella McCartney gown, while Princess Sarvath Al Hassan, the wife of King Abdullah II's uncle Prince Hassan bin Talal, wore a regal mint green sari.

Kate, Princess of Wales, wore a soft blush, high-necked embellished gown by Lebanese designer Elie Saab. The gown is decorated with tone-on-tone lacework and features discreetly sheer panels in the skirt, which falls to the floor.

Britain's Princess Beatrice, who attended with her husband Edoardo Mapelli Mozzi, wore a long-sleeved sequined dress by British brand Needle & Thread. Named the Celia dress, it features intricate work in tone-on-tone trailing flowers in pale blue, and the princess styled it with a black belt, Sophia Webster clutch and Ralph and Russo pumps.

Jetsun Pema, the wife of Bhutan's King Jigme Khesar Namgyel Wangchuck, was seen in a traditional Bhutanese dress as she interacted with other guests.

Denmark's Crown Princess Mary wore a cream floral print gown by Erdem. The luxury label was founded in London by Canadian-Turkish fashion designer Erdem Moralioglu in 2005. The princess eschewed the design's original black bow belt for a purple waistband.

Crown Princess Victoria of Sweden attended the wedding with her husband, Prince Daniel, and supported Scandinavian brand By Malina by wearing the label's Alize floral maxi-dress.

Princess Elisabeth, Duchess of Brabant, attended the wedding with her father, King Philippe of Belgium, and wore a fuchsia caped gown by Belgian brand Essentiel Antwerp.

Queen Maxima of the Netherlands opted for a blue gown from Italian fashion house Luisa Beccaria.

US first lady Jill Biden was the last guest to arrive, accompanied by her daughter Ashley. Biden wore a light purple gown by Lebanese designer Reem Acra, which she also sported in April during a state dinner at the White House.

"I look forward to travelling to Amman, Jordan, to join King Abdullah and Queen Rania in celebrating their son Crown Prince Al Hussein's wedding to Ms Rajwa Al Saif," Biden posted on Twitter ahead of her visit.
