Abstract:The objectification theory is applied in the probe of whether skintight clothes could cause greater body dissatisfaction than well-fitting clothes among college girls.First, 120 college girl subjects imaged themself showing up at different situations in skintight or well-fitting clothes, and were then asked to complete the Body Image States Scale.At the same time two kinds of subjects were designed to find out about the moderating effect of the trait body dissatisfaction.The research was a between-subjects design of 2×2.it is found that the group wearing skintight clothes are found to have greater body dissatisfaction than those wearing well-fitting clothes within the group with body satisfaction;yet no significant difference is found between the two within the group without body satisfaction, indicating that the wearing of skintight clothes can lead to the increase of body dissatisfaction among college girls.
