What social aspects of life and the world does Chaucer seem to emphasize in his descriptions of the pilgrims?

Chaucer uses a character's external appearance to tell us about that person's inner nature. For example, the Wife of Bath has wide hips, wears red stockings, and is gap-toothed, all which say something about her bold sexuality. The Clerk is thin and doesn't dress well because he spends all his money on books, showing he isn't frivolous and loves learning. The prioress wears an emblem that says Amor Vincit Omnia, which means "love conquers all," and dresses much too nicely for a nun who has taken a vow of poverty and chastity. We learn that she is more concerned about her appearance and living well than she should be.
