Why do men cross dress? Mike Williams interviews Helen, a London Underground train driver, Peter a detective novelist - who prefers dressing as Penny - and Peter’s wife who helps to choose the clothes and decide Penny’s look. He talks to the artist Grayson Perry about the relationship between his art and cross dressing. He also poses the question why is it that western society accepts men in kilts, priests in cassocks but has issues with men in skirts?
