How Halston's Costume Designer Re-Created Every Iconic '70s Style Moment to a T

"The first time I tried Halston's double-faced wool trench coat on Ewan, he was obsessed with touching it because it was made of this really beautiful, black cashmere," San Juan recalled. "One of the things people who knew Halston personally told me was that he owned the best of the best in terms of fabrics, down to his shoes — he really only wore exquisite textiles. Through looking at pictures of him over the course of his life, I realised his silhouettes didn't change a lot, so I decided to remake that coat in white. He entered this period of his life where he started doing a lot of cocaine, skewing his palette more towards white, which felt so ultra disco. I played with little details in terms of length and time period to help age or de-age him. But Ewan loved this coat so much that I think he helped manifest it in white, and then later in red, because he loved working with it on camera and he just felt more glamorous wearing it."

When I talked to Venezuelan-born actor Gian Franco Rodriguez, who stars as Halston's love interest Victor Hugo, he was delighted to call out the pieces that really helped him slip into character, which included his jockstrap and the bracelets he stacked on his wrists. His favourite outfit, hands down? "The fur jacket with the see-through mesh, diamond top, white jeans, and white boots at Studio 54. That outfit made me feel like such a rock star. At some point I mentioned I just wanted to shoot every scene in the show wearing that. I still wish I could just go to sleep wearing that coat every night. How could somebody start the day on a bad note waking up like that?" he said, going on to explain how his character affected the presence he brought to his looks. "Victor loved the spotlight, he loved being exposed, so there was plenty of material for me to look at that told me a lot about his personality. I am wearing a jockstrap in every scene, regardless if I undressed or not. The boots also became a character thing for me and they affected my way of walking. I enjoyed making those discoveries in the process."
