The film plays with time to accentuate the families’ economic differences. The Bennets’ clothes are stuck in the 1790s, while Caroline Bingley wears styles from after 1800. Audiences may not detect the difference, but Bingley’s country neighbors do. At a second ball, women ditch their earth-tone dresses for dignified white gowns like the one Caroline Bingley wore to the first one. Everyone is trying to catch up with her.
