Research Paper Topic

For my research paper, I am interested in writing about clothing advertisements and their development throughout history. I plan on focusing specifically on common, well-known brands such as Gap or other common clothing manufacturers, to see how their advertising pattern has developed and changed over time. I will focus on the types of models used, the overall look of the ad, in addition to the clothing styles chosen. I suspect to see a trend, reverting back to old styles and icons as time goes on.
