Secret parties, sly booze and slinky cocktail dresses are a long way from the conservative images usually associated with the Islamic Republic of Iran.For decades the Republic's morals police have enforced strict rules that seem to cover just about everything, from dog ownership, which is banned, to clothing.Drinking alcohol is punishable with 40 lashes. Repeat offenders can face the death penalty.Despite the rules, many young people in Iran are rebelling. They're taking their lives in their hands and defying the regime to party in secret.
