Why do some urban women dress more plainly than rural women?

The plainness of urban women and the plainness of rural women are not a concept of plainness. Rural plainness is because of the rural style, which is plain. And the urban plainness pursues generosity and is beautiful in its simplicity. They may have long been tired of the luxurious life. That's why the simplicity is pursued. So women in the city feel more plain than rural women dress.
