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.

The growth accelerator period from a child's body into an adult body is a huge transition characterized by rapid growth in the near term. Body shape changes at this time of growth should be continually studied because they can result in different outcomes due to various variables. This study is basic study for the production of a junior brassiere patternmaking was conducted to separate the upper torso and breasts of adolescents by growth level. Analysis was conducted by age classification according to sales trends. In this study. 3D body shape data of Korean girls, Based on the 6th Size Korea data, analyzed statistically the upper body and breast according to the rate of growth. The results of this study represent the basis for the development of a junior brassiere to help lead a better life in regards to clothing. The study used 3D-data from girls aged 13 to 18. The analysis indicates that the upper body is in a different shape at age 15 with an increasing circumference, width and shoulder length of the chest; in addition, the sides are analyzed differently, suggesting that the brassiere configuration should be made differently at age 15. The breast form also showed different growth patterns at age 13 and the result was that the shape of the cup in brassiere should be configured differently depending on type.

The purpose of this study is to analyze and classify breast shape of women aged 11~15 using 3D body scan data. In this study, 250 women's body scans were selected from the 6th Size Korea dataset, and 30 items from each of the scan were measured using RapidForm XOR 3 program. The principal component analysis and cluster analysis were conducted using statistical program SPSS 17.0. The five principal components were identified; breast drooping and breast capacity, size from chest to under bust area, breast protrusion, breast height, and under breast angle & outer distance of breast. As the results of cluster analysis, woman's breast types were classified into four types. The breast type 1 was protrusion type (25.1%) which is considered as the breast maturity stage. The breast type 2 had the most drooped breast covering a large area (20.2%). The breast type 3 had the least prominent breast with a highest nipple point, which was considered as the early breast development stage (38.9%). The breast type 4 had the obesity of the chest and breast circumferences with the slightly prominent and the least drooped breast (15.8%). This study can provide fundamental information to develop sizing system and brassiere pattern for junior girls.
