With four Oscars, five BAFTAs, and a Tony Award to her name, Catherine Martin is among the most prolific designers in Hollywood. She works in the theater, film, and interiors, and she frequently collaborates with her husband, the producer, director, and writer Baz Luhrmann. “CM,” as she’s known, has designed memorable costumes for The Great Gatsby, Moulin Rouge!, and Romeo + Juliet, and this month she tackles the aesthetic legacy of an American musical legend with Elvis. To create the costumes for Elvis and Priscilla Presley, as played by Austin Butler and Olivia DeJonge, Martin collaborated with Prada and Miu Miu designer Miuccia Prada on a collection of looks that are guaranteed to bring the Swinging 60s—and 70s—back into the forefront of fashion. Herewith, Martin shares her key components to the good life. —Ashley Baker
