Given the impact she's had on the fashion industry—"Our shining hope for the future!" says Isaac Mizrahi—you won't be surprised to hear a Michelle Obama style guide is coming out in a few weeks. Glamour has a few pages from Michelle Style: Celebrating the First Lady of Fashion, which comes out on May 5 and features "designer sketches, interviews, and style tips" by the likes of Carolina Herrera, Sonia Rykiel, Jason Wu, Catherine Malandrino, Tommy Hilfiger, Behnaz Sarafpour, Isabel Toledo, and Tory Burch. "Michelle Obama is a true independent. She isn't locked into wearing couture or super expensive clothes," explains Nicole Miller. (She is, however, locked into wearing whatever happens to be carried by Ikram Goldman's store in Chicago, but that's another story.) A few sample pages are below.
