The purpose of this research was to investigate the effect of appearance perception on sportswear benefits sought, evaluative criteria, and sportswear image preferences. The subjects were 530 female sportswear consumers who were residents in Seoul. The data were analyzed by factor analysis, multiple regression, ANOVA, and Duncan test. The results showed that there were two appearance perception factors: appearance interest and weight interest. Sportswear benefits sought had five factors of ideal figure/sex appeal, status ostentation, individuality/fashion, comfort, and youth-orientation. Sportswear evaluative criteria consisted of function, brand/fashion, and design factors. Sportswear image preferences had four factors: innovative, luxurious, simple, and active. Statistical analyses showed that there were significant effects of appearance perception on sportswear benefits sought, evaluative criteria, and sportswear image preferences. For example, the consumers who were interested in their appearances sought the benefits of ideal figure/sex appeal, status ostentation, individual/fashion in sportswear. Also, they considered brand/fashion and design as important criteria and preferred innovative and luxurious sportswear images.
