If you watch in awe as beautiful and hideous fads alike sweep the catwalks, streets, and store, and wonder how it all happens, this book, Anatomy of a Trend, by trend sociologist Henrik Veilgaard, is for you. Think of it as a more in-depth look at the scene from "The Devil Wears Prada" when editor in chief of Runway magazine, Miranda (Meryl Streep) breaks down the cerulean trend for poor Andy (Anne Hathaway).
