As a self-described “image architect,” Law Roach is single-handedly responsible for styling Zendaya’s daring looks, as well as Celine Dion and Lindsay Lohan’s career comeback transformations. While he has no formal training, Law managed to become one of the most influential stylists in the world through sheer grit and instinct. Now, he’s released a new book, “How to Build a Fashion Icon,” which is both a memoir and a manual. Law joins Tom to tell us how thrifting with his grandmother helped him cultivate his style, how he rigged the “Who Wore It Best?” columns to put Zendaya on the map, and why he decided to announce his retirement at the height of his success.
