The study aims to explore and discuss the consumption values in the fashion culture of the Tweens, who are unique and self-centered. By observing the dressing style of the Tweens' fashion culture, the researcher looks into the relation between the fashion culture and the consumption values. Interview and observation are employed as research methods in this study. The result shows that, except, for the five aspects brought up by Sheth Newman Gross, the tweens, through their dressing style, create new consumption values which further realize the aspect of self-identification. In addition, through their dressing style, the tweens develop their own fashion trend in the process of continual modification.
