For all the feminist jabber about women being victimized by fashion, it is men who most suffer from conventions of dress. Every day, a woman can choose from an army of personae, femme to butch, and can cut or curl her hair or adorn herself with a staggering variety of artistic aids. But despite the Sixties experiments in peacock dress, no man can rise in the corporate world today, outside the entertainment industry, with long hair or makeup or purple velvet suits.
