The House of Mirth (2000)

Lily (Gillian Anderson) is a ravishing socialite who quickly discovers the precariousness of her position when her beauty and charm start attracting unwelcome interest and jealousy. She seeks a wealthy husband and, in trying to conform to social expectations, she misses her chance for real love with Lawrence Selden (Eric Stoltz). Her quest for a husband comes to a scandalous end when she is falsely accused of having an affair with a married man and is rejected by society and her friends.
