We examined the difference of wearing image through an experiment using one-piece dresses, Dress A and Dress B. The dresses were identical in shape, style and material, but were of contrasting colors. The test subjects were six female students. Forty female students gave third person evaluations of the wearing image of the test subjects, and the test subjects did self-evaluations. An analysis was made using the semantic differential method. The results showed a significant difference was recognized between Dress A, having a bright and clear color, and Dress B, having a dark and dusty color. Furthermore, an electroencephalograph measured the brain waves of three subjects wearing both Dress A and Dress B. It was recognized that the appearance ratio of a waves called relax waves was significantly higher when wearing Dress A which had a bright and clear color. Thus, we obtained results which supported the evaluations of wearing image.
