The purpose of this study was to investigate the wearing situation and satisfaction of school uniforms with the middle and high school boys and girls, who have been in uniforms for one or more years. The subjects for the survey were a total of 560 from the 2nd and the 3rd grade of the middle school, and the 1st and the 2nd grade of the high school. The survey was performed with the questionnaire of 60 questions; 36 questions related to the actual status, such as the purchase, size, repair, and design of a school uniform, and 24 questions related to satisfaction. The results were as follows; 1. Regarding the school uniform purchase, middle school students attached importance to famous brand, while high school students valued design above everything else. The students confused with the school uniform sizing systems were 82.1 % and 72.5 % in middle and high school students. 2. 43% of middle school students and 34% of high school students had experiences of repairing their school uniforms. Regarding the reason for repair, the size misfit was the highest. Boys preferred a single breasted boxy jacket with middle hip line length, and straight trousers, and girls preferred a fitted jacket of waist line length, and flare skirt of the knee line length. 3. School uniform satisfaction score showed that students were not satisfied with their school uniforms so much. Middle school students had significantly lower satisfaction about the design and psychological protection than high school students. Even though high school students showed lower satisfaction about the price and the care of school uniforms, there were no significant differences between them.
