Ten minutes into Halston, Netflix's latest must-watch series, I knew I was going to love it. The '70s fashion! The New York backdrop! Ewan McGregor in a patent trench coat! I was long overdue an escapist TV fashion moment (The Queen's Gambit feels like a long time ago), and this well and truly satisfied that craving. Set in New York in the 1970s and '80s, the series centres around the life and era-defining work of fashion designer Roy Halston Frowick, aka Halston, who is played by Ewan McGregor, and his struggle to steer his eponymous fashion empire.
