2·30대 저체중 여성의 상의 치수체계 제안

This study helps out-size consumers purchase tops and improve the fitness of unde-weight women in their 20s-30s and by the establishment of a size system. The criteria for subjects in this study were those under 18.5($kg/m^2$) of the BMI; subsequently, a total of 233 females were enrolled. The results were: First, the nominal size for female adult formal dress suggested by the KS standard is suggested in 20 sections. The sections for underweight women are 7, (34 women who accounted for 14.59% out of 233 in total). The cover efficiency was 2.08% (which was very low). Second, tests showed that the average difference between the reference part body size of 7 sections for underweight women in the normal size section of bust cir.- hip cir.- height, and KS standard, waist cir. among reference sizes was rather small in the case of a nominal size for long height. Therefore, there is a significant difference with size in the KS standard and a sizing system proven improper for underweight woman. Third, the basic body sizes and reference body sizes were different due to the size system establishment according to measurements of underweight subjects. The research findings suggest that it is necessary to understand underweight types according to bust girth and hip girth sizes that represent basic sizes as well as to design patterns that consider the underweight body shape characteristics when women's tops are designed.
