The research subjects of this study were 30 unmarried Korean women from 20 to 29 who had never had an operation on their breast. Measurement method using plaster breast mold was used for measuring their volume of breast. The correlation between their breast volume and the methods to set up brassiere cups with the existing method and with their circumference of breast was analyzed using KendalI's Coefficient. which was to figure out a method which had a bigger correlation with the volume of breast between the method to set up brassiere cups using the existing method and the method using the circumference of breast. The results analyzed showed that the coefficient of correlation between the existing method and the volume of breast was .12 and the significance level was .45. They didn't have any correlation. On the other hand. the coefficient of correlation between the circumference of breast and the volume of breast was .82. which was very high values and the significance level was very high .0001. Therefore. it turned out that it was difficult to set up brassiere cups by using the existing method and it was easier and more reliable to set up the cups by using the circumference of breast.

This study used 3D technology to develop a multi-functional sports brassiere with increased comfort and fit that can be worn as a base layer during exercise or as underwear. A 75A size industrial lingerie figure was used to develop a standard pattern. 3D tools for scanning and pattern making, such as Vivid 910, Geomagic Design X, 2C-AN and Yuka CAD were used. The sports brassiere was designed as a tank top style with dual structure and linings attached to a pad utilized with a sport brassiere mold cup. 3D outer and lining's pattern was differently developed in consideration of the body's curvature with pad's shape and structure. Shoulder and neck part reduction rates were adjusted to increase the neck areas fit that considered the nude pattern's structure due to uncomfortableness felt by wearers who were uncomfortable with the neck areas fit on existing brand products. The reduction rate was also set differently on each part. For example, the reduction rate on outer side panel was set strongly to increase the breast's volume. Two products, developed by a 3D sports brassiere and previously released product, were worn on 8 subjects in their 20's to evaluate fit, comfort, and purchase preferences. The evaluation proved that newly developed 3D products were superior to comparative products. The results of the clothing pressure measurement indicate that the newly developed sports brassiere's front part had less pressure on upper bust and shoulder areas compared to comparative products as well as showed less pressure on the back side, which shows improved wearing comfort compared to comparative products.

This study is on the brassiere of reduce clothing pressure. To set the measurements of bras for women in their 20s, considering the comfortableness in wearing and tightness, this paper conducted a questionnaire survey concerning breasts and bras as well as measurements of body and contact surface pressure. As a result of comparing the discrepancies between the lower chest circumferences of the body and the bra, it was revealed that 67.0% were wearing one that was bigger than the body size. Most of them mentioned 'feeling of tightness' as a reason(60.4%), which suggests there are problems of the total length and elasticity in the process of making bras. The favorite bra types are wire type(57.9%), mold type(24.3%), and strapless type(10.4%).it is recommended that the total length of lower chest circumference be increased. The result and the recommendations of this study are as follows: First, the total length of brassiere be increased by 5cm from the current patterns in the process of manufacturing. Second, elasticity of the lower-side tapes be extended from 120% to 170%.

This study analyzes the shape change of the breast according to the replica combination method of the lower cup and suggest a pattern construction for the end use purpose. To provide appropriate brassiere patterns to each individual who has various 3D shape characteristics, the ways of layout of 3D replicas were investigated as well as evaluated subjectively and objectively. As for experimental brassieres, basic replicas from the mold cup of long-run brassiere were combined into five different ways to find the appropriate lower brassiere cup pattern. Eighteen women wore experimental brassieres and their breasts were analyzed using the Geomagic Design X program (3D System, Inc., Korea). As result, the pattern that matched the vertexes of the four pieces of the replica and naturally spread the bottom part was best for raising and pushing toward the inside breasts. The fit was good in the case of a pattern in which the convex portions overlapped both sides of the four replica pieces where the vertexes and the bottom part naturally spread apart. The subjects were able to differentiate comfortably fitted brassieres and highly functional brassieres.

This study evaluates the fitness of brassieres through size measurement, comparative pattern analysis, cross section map analysis, 3-D shape analysis number, and fitness evaluation with a focus on domestic and overseas brands. Experimental brassieres were selected as mold brassieres of 3/4 cup in 75A size that is considered a popular design. Brands of selected brassiere were 2 domestic brands (A, B), 1 licensed brand (C), and 2 overseas brands (D, E). Subjects were 8 women in their early 20's. Data were analyzed by descriptive statistics, analysis of variance, reliability analysis, and factor analysis. The results were as follows; the size and pattern of brassieres showed a difference by each brand even though brassieres are the same design. In the wearing effect of brassieres, overseas brand brassieres played a major role in the breast-up effect, but they were not appropriate for the somatotype of Korean women. Domestic brand brassieres showed the volume-up effect, that was confirmed by the increasing bust circumference, bust depth when subjects wore it. In addition, the licensed brand brassieres showed the correction effect of body shape. Therefore, when purchasing a brassiere, the most important condition is to consider the individual characteristics of the somatotype. The results of factor analysis through a functional evaluation show that wearing satisfaction, size satisfaction, and the position of the bust point were important factors for fitness satisfaction and purchase.

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.

With comparative analysis of running-type brassieres on the market about suitability for middle-aged women, this study is to provide basic data of running-type brassieres' pattern which is highly suitable. In the pursuit of this purpose, this study carried out wearing experiment targeting 3 middle-aged women with normal body shape which is 85B of chest circumference. The result is as follows. The significant difference was recognized in the breast. The products were rated in order of C>A>B>D, E, F, G>H by the observers, and C>B>D>A>F>E=G>H by the subjects. The significant difference was recognized in the armhole area. The products were ranked in the order of C, D>B, G, E>A, F, H by the observes and D, C>B>G>F>A>H by the subjects. The significant difference was also recognized in 6 categories(14~19) for the torso. According to the overall average values, the products were rated in the order of B, C, D>A, D, F, G by the observers and B=D>C>H>F>G>A>E by the subjects. The overall evaluation exhibited the significant difference. The products were ranked in the order of D>C>E>B>H>A>G>F by both observers and subjects. Therefore it was confirmed that the product D was appropriate in general. To conclude of comparative analysis about 8 kinds of running-type brassieres on the market, the average values of the product C and D in all categories had high marks for each category. The product C was comfortable and capable of covering the breast well, however, a gap was formed in outside-up part. The product D, made from lacy fabric, was very comfortable and well-fitted but there was inconsistency between the mold-cup and the breast shape.
