Marc Jacobs made his name, and lost his job, with a grunge collection for Perry Ellis in 1992 that helped to normalize the idea of street clothes on the runway. His signature mix of vintage inspired street style and technical proficiency is a proven formula. Why mess with a winner. The Marc by Marc Jacobs Pre Fall 2014 leans heavily on this formula with layers of plaid, abstract prints and artfully distressed casual wear, topped with a chunky crocheted beanie. The collection definitely “Smells Like Teen Spirit” but there’s plenty here to keep us coming back.
