The purpose of this study was to define Korean adolescent girls' brassiere size demand features in order to improve the suitability of junior brassieres for adolescent girls. The subjects for the data collection were Korean teenage girls from age 13 to 17 (n=492). Their body size was collected by conducting anthropometric measurement. The results of this study show that not only the growth of height, but also the growth of the body length is almost finished at the age of 15. The brassiere cup size, which shows the breast growth directly, increased remarkably at age 13 to 14, and once again at age 17. The demand for brassiere band size 70 appeared generally high among all ages. The research also suggests that the band size 60 and over 85 is also needed among the teenage girls. In matters of the brassiere cup size, junior brassieres over B-cup size are also necessary for teenage girls with big breasts to support their heavy breast weight. These results imply that the junior brassiere companies should improve their brassiere size range to fit the teenage girls' breasts properly.

The purpose of this study was to investigate the suitability of brassiere size and wearing habits of Korean adolescent girls. Subjects were 13 to 17 years old girls (n=282). The data was collected by anthropometric survey and qualitative questionnaire survey. Anthropometric survey measured bust and under bust girths; Qualitative questionnaire survey focused on the practice of purchasing and wearing of brassiere. Two general conclusions emerged: 1) Majority of Korean adolescent girls wore a smaller sized cup than their breast volume 2) Korean adolescent girls wore a larger sized band. These results show the need of educating Korean adolescent girls for their appropriate brassiere size and fit. The value of the brassiere that Korean adolescent girls place differed by age. While the younger adolescent girls expected their brassiere to prevent showing the breast vibration, the older adolescent girls expected their brassiere to avoid breast sagging. The older aged adolescents more valued the fit and style of the brassiere compared to the younger aged group when they purchase brassiere. The younger adolescent girls were more likely to be dissatisfied with the fit of the cup. These results reveal that the junior brassiere should be designed to fit adolescent girls' breast shape and size.
