Ruffian designers Brian Wolk and Claude Morais are releasing a behind-the-scenes coffee-table book this spring, written with Style.com editor Nicole Phelps. Titled Ruffian: Inside Out (Assouline, $18.95), the photo-heavy tome chronicles the creation of the duo’s spring and fall 2008 collections, from sketches and fittings to runway shows. (Ogle the full fall collection here.) The book’s official release date is April 15, but a limited number of advance copies will be circulated during Fashion Week. Click ahead for a sneak peek.
