In the design of stereoscopic clothing items, the 3D shapes of the space between clothing and body (SCB; Space shape between Clothing and Body) can be very important clues to improve the fit for various body shapes. Therefore, this research suggests a method for extracting the shape of SCB using the mold bra cup as an example. The SCBs were extracted from two kinds of 3D images, a small-breasted women's nude breast images and bra-wearing images. The the mold bra cups were compressed by wearing, and the outer and lower part of the SCBs could not be obtained because of the movement of the breast volume in the bras. Therefore, the SCBs could not be applied to the design of the mold bra cups directly. However, the suggested method can be useful when it is applied to stiffer clothing items and body parts whose shapes are not changed easily, such as a helmet or other body protectors.

To provide the basic information of the brassiere development for women with poor breast, we performed the survey on their wearing habits for brassieres by comparing the poor breast type women and the normal breast type women. Also, to suggest the advanced design methods for the mould brassiere for the poor breast women, we conducted the subjective wear test of commercial mould brassieres and measured the local thickness for mould cup under various loads. As the results, the good fitness of cup and wire, the natural wear silhouette, and the adaptation of soft and stretchy material for mould cup were very important to design the comfortable brassiere for the poor breast type. The good-fitness of upper cup was the key factor for the satisfactory wear appearance of brassiere and the cup should be designed not too thick at the upper and the bust point regions.

In this study, we proposed the Bustier which improves the fit and functionality to compensate the physical defects by maximizing the volume up effect using the breast detailed measurements and shapes of the poor breast female subjects. Based on the preliminary study of the problem and preference according to the characteristics of the poor breast women consumers, we produced 1/2 volume mold cups based on the previous research. Respectively. A total of 5 subjects were selected, and new 3 bustier patterns based on the pattern making system of industry were created through direct measurement and shapes. As a result of verifying the usability of the developed bustier by testing the commercially available bustiers and the newly developed bustiers for 5 subjects. In order to compare the existing bustiers with the newly developed bustiers, the appearance evaluation by the expert, the evaluation of the adaptability and satisfaction by the subjects were utilized. Through this experiment, the newly developed bustiers were superior in the evaluation of the motion adaptability and wear comfort as well as appearance test. It was shown that the wear effect of the bustier with the longest back length was the best.

Gaps between the upper edges of brassiere mold cups and the breasts are one of the most serious issues in realizing comfort wearing of commercial brassieres for small-breasted women. The surplus ease amounts causing the fit problem were measured from 3D wearing images of the small-breasted women's brassieres. The effect after the removing the surplus ease amounts from the upper edge of mold cup was approved by subjective wearing evaluation. Since the volume distribution of mold cup can also affect the wearing sensation of brassiere, the subjective wearing sensation was compared for two brassieres of different volume distributions, V_L, of which volume was concentrated at the lower cup, and V_C, which has the thickest part at the nipple. As the results, the suitable sensation for cup volume and the natural wearing silhouette could be accomplished by removing the surplus ease amounts from the upper edge of mold cup to reduce the gaps between brassieres and the breasts, which could be accomplished through an approach reducing the volume near the upper edge of mold brassiere cup and making the volume concentrated at the lower cup. These works provide a useful information on the design of the brassiere mold cups for small-breasted women. Moreover, modeling methods of 3D scan data and 3D printing technique for making more accurate mold cases used in this research can be helpful to develop and evaluate clothing products in future.

The ratio of small-breasted women occupies over 20% among Korean women in their twenties. However, the commercial brassieres for the small-breasted women were not fitted well to their breast shapes. In this research, the various commercial mold brasseries for small-breasted women were evaluated through the wearing test and the analysis of 3D images which were scanned from their torsos wearing the brassieres. In addition, professional panels performed the appearance evaluation based on the 2D front and side images captured from 3D images taken by 3D measurement systems. As the results, we found that small-breasted women preferred a 3/4 cup brassiere, of which volume is concentrated in the lower cup. The most preferred brassiere in wearing state shows that the characteristic angle between the chest and the upper cup is about 167 degrees, which is smaller than those of another brassieres, and that the ratio of the radius of curvature of the nipple part to that of the lower cup was about 0.78. These results provide important implications regarding the design of mold brassieres for small-breasted women in spite of the fact that these results represent the selected set of commercial brassieres. Therefore, further studies are highly demanded for the most suitable design information of mold cup for small-breasted women.

The purpose of this study is to survey women′s poor breast shapes depending on their ages and breast types, and thereupon, analyze the differences and correlations among them, and thereby, provide for some basic data useful to the development of the comfortable brassiere which can serve to correct the poor breast. 1. As a result of categorizing the types of schematic breast sides, "type 1" was characterized by medium lower part, greatest pro trusion of breast itself, volumed upper part and visible breast outside, while "type 2" be characterized by medium lower part, most flatness, poor upper part, smallest outside size and medium outside, and "type 3" was characterized by least poor lower part, medium protrusion of breast, poor upper part, medium outside size , and "type 4" was characterized by poorest lower part, medium protrusion of breast, poor upper part, medium outside size and poorest outside. 2. The breast locations could be categorized depending on brest side types; "type 1" a higher location of breast than the other types, "type 2"had a lower location of breast except for the nipples thant the other types, "type 3" had the lowest location of breast and "type 4" had a comparatively low location of breast but had the highest nipples.

To identify optimized thermal properties of mold brassiere cup for improved thermal comfort during summer, we compared the thermal resistance and the water vapor permeability of Polyurethane (PU) foam, 3D spacer fabric and the two combined materials of the PU foam and the 3D spacer fabric. Four experimental mold brassieres were made of the materials for wearing test. Six women in their twenties evaluated the wearing sensation in the hot and humid environment. The changes in microclimate temperature and humidity while wearing test brassiere cups were measured. Results indicate that thermal resistance increased as more PU foam were combined, while the water vapor permeability was higher as the content of the 3D spacer fabric increased at thickness of 18mm and over. However, in the wear test, the PU foam brassiere was the most preferred in all ambient conditions due to its soft, flexible and smooth texture, despite its high thermal resistance and low water vapor permeability. This indicates that the textures of mold foams are more dominant properties than thermal properties for mold foams in determining the wear comfort of mold brassieres.
