Which diffusion type best explains how a fashion trend can spread from major fashion capitals to smaller towns?

• A. Contagious diffusion spreads through proximity from person to person.
• B. Migration diffusion spreads via movement of people.
• C. Hierarchical diffusion spreads via an ordered sequence of places from larger to smaller places.
• D. Stimulus diffusion occurs when ideas are adopted locally.

Answer: (C)

Hierarchical diffusion is the idea that ideas and innovations spread from higher-order places to lower-order places in a ranked sequence. Fashion capitals act as hubs where new styles are created and showcased, so the trend moves first to other large cities and regional centers, then to smaller towns as media, retailers, and trendsetters pick it up. This top-down flow with a time lag matches how a fashion trend typically travels, starting in major urban centers and cascading outward. It’s less about neighbors already nearby spreading it quickly (contagious diffusion), about people physically moving ideas with migrants (migration diffusion), or about ideas being adapted locally while following a non-ordered path (stimulus diffusion).
