<DIV>Ever since a leather-jacketed Marlon Brando slouched across the screen in <I>The Wild One,</I> the jacket's mixture of animal magnetism, brooding menace, and sexual provocation has made it a must-have for hipsters, rebels, and <I>fashionistas.</I> This entertaining book chronicles the leather jacket from its roots among World War I flying aces to its present incarnation in high fashion. Along the way, it shows how every generation and subculture ? including the Hell's Angels, beats, punks, movie stars, counterculturists, and fetishists ? has made the leather jacket its own.</DIV>
