The purpose of this study was to examine whether uniform reforming behavior in high school girls is related to body image distortion, and to obtain objective data to help in guiding students in the wearing of uniforms at school. 661 freshmen and junior girls at six high schools in Kwangju city responded to questionnaires. The data was analyzed by one-way ANOVA and Pearson’s product-moment correlations using the SPSS 12.0 program. According to their body satisfaction level, three groups (haggard distortion, normal, overweight distortion) were identified. The data showed that a few high school girls were unable to recognize their body types correctly. It also indicated that school uniform reforming behaviors in high school girls were not related to their body image or body satisfaction level. So, it seems that students need guidance in the building up of an objective body image and wearing uniforms to fit their body types.
