Madame Hoo
Quote 1
Madame Hoo served in a tight-fitting silk gown slit high up her thigh, a costume as old-fashioned and impractical as bound feet. Women in China wore blouses and pants and jackets. That's what she would wear when she got home. (16.2)
While Madame Hoo is wearing Grace's idea of what Chinese society is like, she's really thinking about how stupid that assumption is. Grace thinks having Madame Hoo at her party dressed up like this makes her look classier, but what it really does is emphasize her prejudice against and ignorance about Chinese culture.
