Kat Irlin Rebecca Dayan was hoping that, after life somewhat returned to normalcy, she would finally get to meet Elsa Peretti, the fashion icon and jewelry designer she portrays on Netflix’s Halston. But she never got the chance; Peretti “It was really sad, because I was hoping that once the world reopened, that I would get to meet with her,” Dayan tells BAZAAR.com over Zoom, speaking from her New York City apartment. She reveres the late Italian designer, perhaps so much so that she downplays her take on her life. “Maybe she would’ve hated the way I portray her,” Dayan jokes. “I hope not.”
