How does Renoir minimize social class in the world depicted in Bal du Moulin de la Galette?

What will be an ideal response?

Answer: The ideal answer should include:
1. Women are dressed in equally fashionable styles regardless of actual social class.
2. The tightly packed crowd does not separate out individuals or create physical distance between social classes.
3. The action and tone of the scene unifies the crowd into one experience regardless of social status.
