This paper examines the psychological and physiological influences the color of clothing has on the wearer. The color of clothing, which is worn directly on the body, has significant psychological and physiological impacts on the wearer. Two case studies of these impacts were carried out : one in which the wearers did not check their appearance in the mirror, and one in which they did. In the study, 15 subjects put on seven dresses of different colors one by one, and their brainwaves, which indicate physiological activity of the central nervous system, and fluctuations in heartbeat, which indicate activity in the autonomic nervous system, were measured. Psychological analysis was performed using the SD method and factor analysis. Results indicate that when the α wave content of the color in clothing is high, the HF component is high and the LF/HF component is low, and the wearers' sense of comfort increases. However, colors with higher "active" factors reduce the wearers' sense of comfort. In this case, when the wearers checked their appearance in the mirror, their α wave content was lower, the HF component was smaller, the LF/HF component was larger, the sense of relaxation was lower and mental stress rose compared to those who did not look at themselves in the mirror.
