In Roots of Style: Weaving Together Life, Love, and Fashion, out March 6 from Celebra, “designer’s designer” Isabel Toledo shares the story of her life and career, including fashion tips, for the first time. In the same volume, her husband—fashion illustrator, fine artist, and reporter Ruben Toledo—also shares his work, a collection of exquisite illustrations that realize his wife’s designs in fluid but unpolished graphics that exhibit a sense of high style and hand-craftsmanship at once. Here, the Tip Sheet previews a handful of those images.
