Lefferts is considered the utmost authority on “form” in New York society. He’s a fashionable, good-looking young man who likes to think that he sets an example for other young men to follow. However, his insistence on members of society following certain rules of fashion and public behavior is largely an act that he uses to cover up the frequent affairs he conducts outside his marriage. In this way, Lefferts represents the worst hypocrisy of New York society.
