The purpose of this study is to examine on breast shapes of elderly women and provide fundamental data for developing brassiere. Numerous anthropometric measurements and other related data from 398 subjects were analyzed by various statistical methods such as ANOVA, Correlation analysis, Factor analysis and Cluster analysis. 1. Analysis of Breast Measurements The subjects were categorized into three groups(Group I; aged 55 to 64, Group II; aged 65 to 74, Group III; aged more than 75). 1) The results of the comparative analysis of anthropometric data from three groups show that by getting older: - $\circled1$ Breast lengths, widths, heights and bust girths are decreased significantly $\circled2$ Various length measurements related to the drooping degree of breast are increased $\circled3$ Some measurements related to the volume of breast are decreased. 2) The results of the correlation analysis among measurement show that there are no directs linear relationships between under bust girth and bust drooping. Further it turned out that the cup size could be used as a factor explaining the volume of breast due to large subject variation, Thus it is required to have more specific information about the breast volume. 2. Analysis of Breast Shapes 1) From 17 measurements, 5 factor were selected as key factors for the factor analysis of breast analysis of breast shapes. The 5 factors are: $\circled1$ Drooping degree of breast $\circled2$ slope between breast and chest, width of bust point $\circled3$ Contours and prominence of breast at the point of front and side $\circled4$ Breast volume $\circled5$ Breast width. 2) We categorized the breast shapes into three types by Cluster analysis. Type 1 is the most common breast shape in elderly women. $\circled1$ Type L: Not too droopy and large breast $\circled2$ Type 2: A little droopy and small breast $\circled3$ Type 3; Very droopy and wide breast

The object of this study was to help designing of well-fit and comfortable brassieres for the elementary school girls through the survey on actual condition of wearing brassieres. The subjects of investigation for this study was the elementary school girls in the province of Jeonbuk and Taejeon city. The conclusion of this study was as follows; The 40.2% of the total subjects were wearing brassieres like the 63.3% of the fourth, the 85.4% of the fifth, and the 89.7% of the sixth grade students. The main reason of non wearing brassieres was for the underdeveloped breast, and also that of wearing brassieres was for the good shape of the breast. The main types of brassieres were ranked "Tank Top type", "Mold type", and "Adolescent girl-Bra". They had started to wear brassieres by the recommendation of adults who were their mother or teachers, and usually wearing brassieres all day. They usually purchased brassieres "with mother together" or "only by their mother". The standard of choosing brassieres was also ranked by FASHION, CONVENIENCE, SIZE, TOUCH, and SWEAT ABSORPTION. The total score of satisfaction for wearing brassieres was showed "Average score" and the score higher in Jeonju and Taejeon than in Kunsan. The higher grade and fatter was showed decreasing the score of satisfaction. The higher grade became, the more various for the size and preferable a pure cotton fabric for brassieres. The favorite types of brassieres were "Sport Bra" and "Volume-up Bra". They usually purchased a little larger size than their original size of that.

The purpose of this study presents bra pattern using the 3D measurements of the upper body subject to women in their 30's. Brassieres available in the market are mostly designed for straight body shape and many women seem to have experienced bearing discomfort in a great extent as they grow older. Brassieres should be designed to cover diverse body types and the accurate measurement of body type and breast shape is needed to accomplish that. As for the study method, 3D human body types were analyzed with RapidForm 2006, and the upper-body types and breast shapes were statistically classified through technical statistics analysis, cluster analysis, t-test, variance analysis, and cross analysis. The wearing tests went through the comparison of the brassieres of three makers in the market and the experiment brassieres(first and second) and then the evaluations were made by the subjects, the outer appearance assessment by experts, and 3D measurements. The results of this study showed that the evaluation of experiment brassieres was excellent in every item, and the significant difference was found out particularly in the items of pressure, rear center, front center, breast underneath, adequate level by wing, and adequate level by armhole. According to the results of 3D evaluation, experiment brassieres had a highest point in fitness with no physical pressure at the wing part and no overall deviation at the cup part.

The current bra market and the purchasing behavior of women of the MZ generation in Korea are reviewed in this study. Therefore, basic data for bra product planning for women of the MZ generation are presented by investigating the wearing status and satisfaction. Through online surveys, 272 questionnaires were obtained and were analyzed through frequency analysis, cross-analysis, t-test, and variance analysis. Generation M and Generation Z share digital culture, but, due to age differences, they are compared by generation. There was, however, little significant difference between these groups. In addition, there was no significant difference between groups when factoring for the time of wearing, place of purchase, and material of bras. However, there were big differences between groups depending on whether bras had wires, lace, and their size, especially in body correction items. According to the results, it is pointless to target each generation when making a bra. Also, the young generation consumers are more interested in functionality than in the design compared to 10 years ago. It will improve consumer satisfaction if two different types of bras are produced; one that corrects the body and one that fits well even if the body is less corrected.

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.

This study is done in Shanghai area by sample survey of female college students in their lower 20s. Through direct contact survey, this study collected and analyzed information on figure to understand feature of breasts and measurements of body to provide base information to improve product of brassiere for adult female in China. Data was analyzed by using SPSSWIN 13.0 Program and SAS 9.0. 1. From a result of factor analysis on 40 items of measures to derive the components of the shape of the breast, 6 factors were derived such as the factors to show the obesity of the bust, to show the ratio of the upper and lower area of the lower bust, droop and volume, to show the internal shape and broadness of the bust, to show the location and vertical size of the bust, to show the protrusion of the bust and the eternal shape of the bust. 2. From a result of classification on the shape of the breast of the Chinese women in their early 20s, 4 types were selected. Type 1 is the protrusion type that a woman has a broad drooped breast due to the development in the upper and lower parts of the chest as well as the highest height, a high degree of obesity in the bust part, big volume and much protrusion. Type 2 is the hemisphere type that the degree of obesity in the breast is second to Type 1 and a breast is located at a region higher than Type 1 as the degree of obesity in the breast is secondly highest, the lower part of the bust is bigger than the Type 1 and the degree of being broad and drooped is second to Type 1. Type 3 is the cone type with a breast of being drooped and broad a little bit and a certain degree of a volume. Type 4 is the flat type with the smallest value in the item that shows the obesity of the bust area and with the smallest value in the R$\ddot{o}$hrer index to have the small and slender body type for the bust area, which is somewhat flat due to a low slope at the internal side of the bust.

This study helps in the production of brassieres suitable for female adults by researching the actual wearing conditions and purchasing status, satisfaction rate, and preferences of female college students in their early 20's. The collected data was analyzed by a SPSSWIN 13.0 Program and the results of the research are as follows. 1. There is a noticeable difference between the breast satisfaction rate and breast size, in addition the satisfactory rate was higher in the normal breast size or a little ample size than in the very small or very big size. According to the shape, the satisfactory rate for the breast appeared to be high in the case of the recognition and evaluation of the hemisphere type than the flat, cone, pop out, and downward type. 2. For fitness, the looseness at the top of the cup (pressed between the breasts at the upper part of the front middle), pressing and looseness at the upper sides of the cup, inappropriate size of the cup, tightness of the wings, tightness at the bottom round of the breasts, the narrow width of the wire, wide space of the shoulder strings, and the sliding of the shoulder strings had problems that needed improvement. 3. The major priorities for purchasing brassieres are size, fitness, and aesthetic qualities. As a result, the size and the fitness are more important than the trend or decorations since the brassiere has the function to support the breasts that shows that hygiene and sanitation are recognized as an important standard for undergarment selection. The size and the fitness are important factors regardless of breast types in the examination of the selection standards of the brassieres for each breast type, but the cone and hemisphere types have higher preferences for design; the pop out type has more considerations for the material of the cloth. The result show that appearance is more important for smaller breasts, but the functionality of the brassier is more important than the appearance for medium and larger breast sizes.

The purpose of this study is to develop the well-fitted brassieres by observing the changes in the breast sizes and shapes, the surface area and the volume of the breast through the arm movements of 3 types (0$^{\circ}$, 90$^{\circ}$ and 180$^{\circ}$) in vertical motion. The subjects are females, who are aged twenties and wearing a brassiere size 70B, In particular, to obtain the measures regarding the surface area and the volume of the breast, replicas are made at each motion. The results of this study are as follows: 1. The changes in the breast sizes and shapes at each motion By increasing the motions of the arm movement, the following measure items are inclined to decrease: Shoulder length, Side neck point~B.P., Front neck point~B.P., Horizontal length of the cup, Upper bust circumference, Bust circumference, Upper bust depth, Bust depth, Under bust depth, Nipple to tipple breadth, Horizontal distance of bust, Bust height, Cup size. By increasing the motions of the arm movement, the following measure items are inclined to increase: Center point of shoulder~B.P., Shoulder point~B.P., Armpit~ lowest point of breast drooping, Upper bust point~B.P., B.P~Under bust point, Under bust line, Width of gap between breast, Vertical distance of Bust. 2. The changes in the surface area and volume of breast at each motion By making the replica to observe changes in the surface area, which are sectioned to 4 parts(area 1 to area 4) , and volume of breast at each motion, the results are as follows: At 0$^{\circ}$ and 90$^{\circ}$, the sizes of each part are ordered as the following: area2> areal> area4> area3. At 180$^{\circ}$, the sizes of each part are ordered as the following: areal> area2> area4> area3. Through these orders, it is found that the upper and inside part of the breast has the inclination to increase so long as the motions of the arm movement increase. Also, the total surface area increases so long as the motions of the arm movement increase. The volume of the breast increase when the surface area of the breast increases. As a result of the F-test on the changes in the each surface areas, the surface area and volume by arm movements, the significant differences among the each surface areas and the surface area are not found.
