Objective: The aim of this study was to develop a method for measuring breast size from three-dimensional (3D) body scan image data. Background: Previous bra studies established reference points by directly contacting the subject's naked skin to determine the boundary of the breast. But some subjects were uncomfortable with these types of measurements. This study examined noncontact methods of extracting breast reference points from 3D body scan data that were collected while subjects were wearing standardized soft bras. Method: 3D body scan data of 32 Korean women were analyzed. The subjects were selected from the Size Korea 2010 study. The breast landmarks were identified by graphic analyses of slicing contour lines on 3D body scan data. Results: Three methods determining bra cup size were compared. The M1 and M2 methods determined cup size by calculating the difference between bust girth and under-bust girth. The M3 method determined bra cup size by measuring breast arc length. Conclusion: The researchers proposed an anthropometric bra cup sizing system with the breast arc length (M3 method). It was measured from the geometrically defined landmarks on the 3D body scan slicing contour lines. The new bra cup size was highly correlated with breast depth. Application: The noncontact measuring method used in this study can be applied to the ergonomic studies measuring sensitive body parts.

This study provides basic information for the convenient size selection of T-shirts in an online purchasing environment. The best preferred T-shirts fit was selected among five sizes of T-shirts according to body size group. The subjects were 103 students majoring in clothing. After setting a virtual model with her own body sizes, the subjects chose the best preferred fit among five sizes of T-shirts that included the one suitable to their bust circumference, two smaller T-shirts and two larger T-shirts. As a result, they preferred the fit of larger size T-shirts than body size, but they preferred a different fit by the body characteristic group such as waist height group and hip circumference group. T-shirt length was affected by waist height; in addition, shoulder ease was affected by hip circumference and bust circumference. Therefore waist height and hip circumference should be considerable sizes when consumers choose T-shirts sizes with a preferred fit.

1. For the purpose of making the basic pattern construction 100 girls attending the Seoul National University College of Home Economics were measured in finding of body size and coefficient of correlation which would be used as one basis of this study. 2. Coefficient of correlation of each body part based on the breast width was shown as follows; Correlation coefficients of bust to waist and hip were high and those of bust to shoulder width, neck height, back width, and breast width were low. None of that was found between bust and back length. It was not recognized so scientific to adjust the basic pattern construction with figures proportioned by those of neck, shoulder width, breast width, and back width. 3. The method of basic pattern construction obtained by this research has been demonstrated in direct wearing since 1967. It is believed that the result will contribute a great benefit in teaching clothing as well as in mass production industry of ready-made garments.

This study sought to typify and characterize the upper body shape of women with large breasts by classifying only Korean adult women aged 20-69 years whose difference dimension between bust and underbust circumference was 12.5 cm or greater. This study attempted to provide necessary information for the development of upper body clothing for women with large busts. Upper body horizontal, upper body height, shoulder size, upper body length, and shoulder slop factor were extracted to constitute upper body shapes of women with large busts. Upper body shapes of women with large busts were classified into four types: low obese upper body tall body type, high normal upper body short body type, drooping shoulders slender upper body tall body type, and broad shoulders slender upper body short body type. Upper body proportions of women with and without large busts were analyzed as follows. Women with large breasts had narrower shoulder width compared to bust width and waist width. Their underbust and waist circumferences were larger than their bust circumferences. For the development of tops for women with large busts, bodice pattern development was required, taking into account shoulder width, chest, and upper body length. Future studies should focus on angles of busts in more detail. Research should be conducted on the development of bodice by upper body type of women with large busts analyzed.

This research developed maternity wear designed with a focus on the essential functions necessary for working women and adaptable to their body changes during pregnancy. Through Martin's anthropometry for 201 pregnant women, the size specifications for maternity wear was determined and a dress form was proposed, in order to provide the manufacturer with reference data and a prototype to verify their products' fit and suitability. From a monthly analysis on the body measurements of pregnant women, significant monthly differences and after pregnancy were found in weight, chest girth, bust girth, under bust girth, waist girth, and hip girth. Dress form was designed based on the average body measurements of women in their 6th to 10th month of pregnancy. The standard dimensions in the 8th month were 90cm (chest), 94cm (bust), 86cm (under bust), 97cm(waist: most protruding part on the side), and 99cm (hip). Compared with Japan's MAT-9 (for nine months), chest girth was the same, while the Korean waist girth and hip girth were larger by 2cm and 3cm, respectively. The woven fabric blouse was evaluated as having the best appearance, while the knitted fabric one was judged as being more comfortable it terms of functionality. For the pants, the design details of the lowered waist and curved waist belt were more functional. The tailored jacket was the best design for working women in terms of both looks and functionality. To summarize, maternity wear for working women, unlike general maternity clothes, should be designed with consideration for the wearer's somatotype and activity. Elastic materials were appropriate for functionality and dealing with physical changes. With the increasing of working pregnant women, such trials are expected to continue in this research area in order to develop functional maternity wear with multi-purposes such as breast-feeding, wearability after delivery and shielding from microwave.

China shows body size differences owing to varied climates, economic development, living standards, and ethnic distribution from region to region. That's why some regional research regarding body sizes is necessary for the advancement of clothing goods into China. Here, the materials of the Chinese standard "GB/T 1335-1997 Clothing Sizes" are analyzed to reveal the somatotypes of Chinese adults. Height, chest girth and waist girth were differently noticed in six areas. 1. The distribution rates of four body types (Y, A, B, C) were diverse in six regions. 2. Regional differences were seen as follows: 1) As for the height of male adults, areas 1(Northeast, Hwabuk) and 2(Central Western) were larger than the national mean. Areas 3(Gwangdong, Gwangseo, Bokgeon), 4 (Unnam, Gwiju, Sacheon) and 5(Downstream Jang River) were rather small. 2) As for the height of female adults, areas 1, 2 and 6 (Midstream Jang River) were larger than the national mean. Areas 3 and 4 were smaller than the average. 3) As for the bust girth of male adults, area 1 was the only area that exceeded the national mean. Areas 3 and 4 turned out smaller than the average. 4) As for the bust girth of female adults, areas 1, 2 and 6 exceeded the national average. The other three areas were lower. 5) As to the waist girth of adult males, areas 1 and 2 exceeded the national average. The other four areas were lower. 6) As to the waist girth of adult females, areas 1, 2 and 6 exceeded the national average. Areas 4 and 5 were lower. 7) In the height, bust girth and waist girth of male and female adults, most regions showed differences in means, regional distribution and regional rates.

This study was to compare and analyze the clothing pressure according to arms movements of 4 brands jacket for middle-aged women group by measuring clothing pressure of each brand. The results were as follows: 1. According to the analysis of jackets of 4 brands, in general, jacket C had the largest ease amount. while jacket A had a large ease amount in waist, hip areas compared with bust area. Also jacket B had a small ease amount in bust, waist areas and jacket D had a small ease amount in hip areas. Therefore the ease amount is different between each brand, each size even though jacket designs are similar. 2. It was found that clothing pressure was affected by arm movements than jackets. Since this study was limited to the arm movement for motion variation, it was recognized that a significant difference among each jacket and each movement at shoulder, waist parts existed with relation to this motion. 3. Parts showing a significant difference among each size were bust point, abdomen point, center back point of abdomen level, angulus superior scapulae point and center back point of waist level. Also clothing pressure of size B91 was bigger than size B88 except Center back point of waist level. 4. Clothing pressure in shoulder point, front armpit point, back armpit point, upper arm point areas increased as the angle of the arms movement increased. Also, individual variation of clothing pressure in front armpit point, back armpit point, armpit point and upper arm point was large, and clothing pressure in abdomen point was high in M5(sitting posture).

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 objective of this study is to examine the current status of manufacturing formal knit jackets for middle-aged women. Fifteen manufacturers specializing in formal knitwear brands were chosen as the study subjects, and interviews and questionnaires were used with patterners and designers. The questionnaire was composed of 27 items and began with general questions, such as how the jackets were manufactured. Specific questions, such as materials and sewing method, were also considered further on. The results are as follows: First, as for the structure of the knit jacket manufacturer, seven out of fifteen manufacturers directly manufactured knit jackets in their own factory, while the manufacturing was comprised of 20% woven jackets and 80% knit jackets for all manufactures. Second, as for the type of yarn mostly used in knitting the fabric for the jackets, satin yarn and wool were used mostly for F/W with Plain and Half Milano rib stitches as the type of knit with a gauge of 12G and 7G. Third, as for the margin between the product size of the target brand and the size of the body at the time of designing a knit jacket pattern, the investigation of the actual state of manufacturing showed that the margin at the bust was B+4.8cm, the waist was W+6.9cm, and the hip girth was H+5cm. Therefore, the bust and hip girth of the knit jackets were designed to be smaller than those of the bust and hip girth lines of non-flexible woven jackets. On the contrary, the waist measurement of non-flexible woven jacket was designed to be smaller than the knit jacket. It was found that the side line of the knit jacket was expressed with greater give as compared to that of the non-flexible woven jacket.

A 3D body scan measurement (SM) is used as an alternative to physical measurements (PM) as the information for designing industrial products. This study compared the mean difference (MD) between SM and PM by gender and analyzed the causes of the difference. The data used in this study were the scan measurements and physical measurements of adults aged twenty to seventy years old of the fifth Size Korea survey. The results of this study are as follows: 1. The comparison of MD between men and women for all subjects: The measurement of the significant differences between men and women were height, neck base girth, chest girth, under-bust girth, waist girth, armscye girth, back length, and foot length. The causes of difference are the difference of body shape. 2. The comparison of MD between men and women by BMI groups: Many measurements had significant differences between men and women at normal weight and overweight but underweight. Some measurements had significant differences only at a specific BMI group because the body shape difference between men and women is revealed clearly in the group. The comparison of MD between men and women by age groups: The measurements that show significant difference at more than four age groups were neck girth, chest girth, under-bust girth, waist girth, armscye girth, and foot length. The height and abdomen girth had a significant difference in the age range of 20's and 30's. There were measurements that increase MD with an increase in age; under-bust girth and lateral shoulder length for women and lateral shoulder length for men. This comparison of MD between men and women provide the correct guidelines for the use of SM.
