The theory of fashion adoption that suggests fashion moves horizontally among social classes rather than vertically would be the horizontal-flow theory. Also known as the mass-market theory.
Answer:
Theory of Mass Dissemination
Explanation: When applied to a society that has a stable class structure with demarcated upper and lower classes, the Traditional Adoption theory works. However, this class differentiation is not easy to determine in modern Western society. The Theory of Mass Dissemination accounts for developments in mass culture. Advances in technology and developed distribution systems help modern customers develop individualized choices. With the Theory of Mass Dissemination, the fashion movement happens in a horizontal fashion, and shifts from one group to another that belongs to similar social levels.
