Despite the number of foreign-born designers showing in New York, they manage to produce little variation in the prototypical woman: she’s either good or she’s bad. Jason Wu, who became famous overnight for his white inaugural gown for Michelle Obama, placed little tiaras on his models, their hair center-parted and their cheeks rosy. His women are resolutely good, with taste — rather than sex appeal — reflected in the checked wool jackets, a lapis blue sheath scattered with French knots, and a gray microcheck cashmere dress with black embroidered cap sleeves.
