elie saab is a king

What one of the Pureborn of Qarth, also known as the Enthroned, would wear, Elie Saab

 The Pureborn are descendants of the Qarth’s ancient kings and queens, who rule the city of Qarth from the Hall of a Thousand Thrones. They are notorious for offering poisoned wine to those they consider dangerous and their avarice is equally well-known. There is a saying among the merchants of Qarth: “It is easier to milk the Stone Cow of Faros than to wring gold from the Pureborn." 
To receive an audience with the Pureborn, a petitioner should make a traditional sacrifice in the Temple of Memory, offer a traditional bribe to the Keeper of the Long List, and send a traditional persimmon to the Opener of the Door. If all goes well, the petitioner will be sent a pair of blue slippers, signifying the granting of an audience in the Hall of a Thousand Thrones.
