The time when fashion was defined by French designers whose clothes could be afforded only by the elite has ended. Now, designers take their cues from mainstream consumers, and creativity is channeled more into mass-marketing clothes than into designing them.

In "The End of Fashion," Wall Street Journal reporter Teri Agins astutely explores this seminal change, laying bare all aspects of the fashion industry from manufacturing, retailing, and licensing to image making and financing. Here as well are fascinating insider vignettes that show Donna Karan fighting with financiers, the rivalry between Ralph Lauren and Tommy Hilfiger, and the commitment to haute couture that sent Isaac Mizrahi's business spiraling.
