The purpose of this study is to verify the accuracy and applicability of a 3D virtual garment system by comparing real and 3D virtual garments according to lower body shape. The researcher designed different patterns to fit the four subjects in the experiment, each having a different lower body type. The participants then tried on the garments to be evaluated. 3D virtual garments were created with the CLO 3D Program, adhering to the specific conditions of the real garments based on 3D body scan data from real-life models. For the evaluation of real and virtual garments, 11 experts assessed the silhouettes by answering survey questions on ease amount, creases, position, silhouette, fit, etc. The questionnaire was designed on a 5-point Likert scale. For technical analysis, deviation, stress, and strain were studied. The expert assessment found no meaningful differences for most of the evaluated items. In fact, the 3D virtual garments received better evaluations than the real garments, as the virtual garment simulations made adjustments for better fit in the course of property calculations, rendering a more sophisticated silhouette and thus improving the look of creases. A quantitative evaluation found that the 3D virtual garments rendered a similar fit to the real garments by suggesting garment pressure and ease amounts with the use of numbers and a color distribution map. Although ease amounts differed to some extent, the fit factors were similarly realized in the virtual garments, indicating that a virtual garment can serve as a reliable replacement for the real thing. 본 연구는 하반신 체형에 따른 실제착의와 3차원 가상착의의 맞음새를 비교 분석하여 3차원 가상착의 시스템의 정확성과 적용가능성을 알아보고자 하였다. 서로 다른 하반신 유형의 피험자 4명을 대상으로 각자의 체형을 반영한 패턴을 설계하여 실제착용 평가를 실시하였다. 3차원 가상착의는 실제 모델을 스캔한 3차원 인체 형상을 이용하여 실제착의와 동일한 조건으로 CLO 3D 프로그램으로 제작하였다. 실제착의와 3차원 가상착의의 맞음새 평가는 11인의 전문가 집단이 외관평가를 하였으며, 여유량․당김/군주름․위치․외관․맞음새 등의 설문 문항을 5점 리커트 척도로 평가하였다. 기술적 분석으로 공극량․응력․변형률을 조사하였다. 전문가 외관평가 결과, 대부분의 항목에서 실제착의와 3차원 가상착의간의 유의한 차이가 나타나지 않았으며, 실제착의보다 3차원 가상착의에서 외관이 좋게 평가되었다. 이는 가상착의 시뮬레이션시, 물성계산 과정에서 자연스럽게 변형되어 정돈된 실루엣으로 표현됨으로써 실제착의에서 나타난 주름들이 좀 더 좋게재현되었음을 의미한다. 3차원 데이터의 정량적 평가 결과, 여유량과 의복압을 수치와 색분포도로 제시하여 실제착의와3차원 가상착의의 유사한 맞음새를 확인할 수 있었다. 여유량의 수치는 차이가 있었지만 실제착의에서 나타난 맞음새 요인들이 3차원 가상착의에서도 유사하게 재현되어 3차원 가상착의의 재현성을 어느 정도 신뢰할 수 있을 것으로 평가하였다.

Three-dimensional virtual fitting has become a trending practice in the fashion industry because of its productivity benefits, allowing garments to be virtually worn by avatar models without physical production. This study analyzed the variables influencing clothing pressure in both real and virtual fittings to expand the potential utility of pressure data derived from the latter. For this purpose, six sets of compression garments were created by combining two types of tricot fabrics and three types of reduced-pattern tops, with the clothing for real and virtual fittings having identical dimensions. Focus was directed to analyzing the correlation among clothing pressure, surface area deformation, and the mechanical properties of the fabrics. In real fittings, clothing pressure was influenced by multiple factors, including garment design, pattern reduction ratio, body shape, and fabric properties, consistent with existing knowledge. In virtual fittings, however, only the digital mechanical characteristics of the fabrics significantly influenced clothing pressure. The findings suggest that a more reliable implementation of clothing pressure in virtual fitting programs necessitates an approach that considers the complex structural information of garments.

The purpose of this research is to compare and analyze visual images between the Real garment and the 3D garment simulation with the various fabrics of flare skirts and to analyze the correlation between mechanical properties and visual images. The picture images (printed on paper) of the Real garment and the 3D garment simulation of experimental flare skirts were shown to the evaluation group of women in their 20s majoring in clothing and textiles, and were evaluated by questionnaires with 32 adjectives. SPSS Version 12.0 statistics program was utilized to analyze data. Factor analysis, One Way ANOVA, T-test and Duncan test were used to investigate visual effect of the Real garment and the 3D garment simulation. As the result of conducting factor analysis on the visual appearance, the images were driven with five factors: ``drapeability``, ``attractive``, ``body compensation``, ``bulkiness``, ``activeness``. Visual images were significantly related with mechanical properties of various fabrics, and the visual images between 3D garment simulations and real garment differed with various fabrics and their mechanical properties. Visual images of silk and polyester group, cotton, linen and wool group were significantly related with weight and thickness of kinds of fabrics.

The purpose of this study was to compare ideal clothing and actual clothing behavior between Korean and Japanese college students. 185 Korean students and 91 Japanese students were used into data analysis from October to December, 2000. The age range was 18 to 28 years. The results were as followed. 1) Japanese students wanted to wear fitted clothing styles with revealing the body, while Koreans wanted wear not only fitted styles but also relaxed and coved body styles. 2) Korean students wore more loose styles and fitted upper styles and pants than Japanese students On the other hand, Japanese students wore fitted clothing styles and skirt. 3) Japanese students showed higher correlation between ideal clothing styles and actual clothing styles than Koreans. This means that although Koreans want to wear ideal styles, they don`t wear those styles much. 4) Overweight students tended to avoid wearing fitted and revealed body styles pursuing more loose and coved body styles. This tendency showd stronger to Korean than Japanese students.

Appreciation of flare skirts is mainly based on its appearance when put on, in other words, its drape of which the selection of fabric is most decisive. There are a few other dynamic characteristics affecting the drape like bending stiffness(B), bending hysteresis(2HB), shear stiffness(G), shear hysteresis(2HG), weight(W) and so on. This study is aimed to investigate how the dynamic characteristics of fabric will affect the three dimensional quality of a semi flare skirt-a major item of 'feminine look' brought into fashion in S/S season of 2008. To see how exactly dynamic characteristics of fabric is simulated in the imaginary dressed condition by 3D Virtual Garment Simulation currently applied to various fields is another object of this study. This can help us find out how close we are now to the time of mass-customization. It is resulted that Plain weaved fabrics which has the lowest bending rigidity(B) and bending hysteresis(2HB) is pliable and soft and accordingly enables the silhouette which can emphasize the body shape, whereas the 5H Satin weaved fabrics which has the highest value is difficult to bend and tends to form the box type silhouette maintaining rooms from the body. 4H Twill weaved fabrics is evaluated to have more shear stiffness(G) and shear hysteresis(2HG) than 5H Satin weaved fabrics. 5H Satin weaved fabrics which has the lowest shear stiffness(G) and shear hysteresis is expected to have good drape with its excellent harmony with human body shape by providing the deflection and tactile sensation. When the thickness and weight of the blending rate is compared, Plain weaved fabrics is thinner and lighter than 5H Satin weaved fabrics, and the greater density of the fabric tends to have thicker and heavier characteristics. As the smaller the drape coefficient is in the range from 0 to 1, the better the drape becomes. It is determined that the 3H Twill weaved fabrics with the lowest value has good drape and Plain weaved fabrics has poor drape.

In order to investigate the influence of being self-consciousness of ones body size on clothing behavior, we measured body size of Korean female college students directly and examined by questionnaire the degree of being self-consciousness of their body size, the aspired clothing behavior, and the actual clothing behavior. In addition, after classifying the subjects into groups according to the degree of obesity, we also examined the difference in the actual clothing behavior among the groups. The results are as follows ; 1) On the item of girth of the body parts, the subjects felt thicker in the proximal and lower part of the body than in the distal and upper part of the body. And with respect to the style which exposes body silhouette, the disparity between the aspired and actual clothing behavior was greater in the parts that the subjects felt thick. 2) After investigating the relationship between the aspired and the actual clothing behavior, we found out that the style which subjects wanted to put on but actually did not was the style that exposes body silhouette, and the style which subjects didn't want to put on but actually did was the style covers the body silhouette. 3) There was significant correlation between the subjects' consciousness of their body size and their actual clothing behavior. The self-consciousness of body size on actual dressing tend to influence the clothing for lower body more than the other parts. 4) The subjects were classified into lean, normal and obese groups. There were significant differences among the groups in the frequency of wearing the clothing that expose body silhouette. The obese group had a tendency to avoid this clothing style.

This study aims to examine for efficient production methods of custom-tailored clothing and application of 3D virtual clothing system in custom-tailored clothing market, by producing and analyzing both real clothing and 3D virtual clothing. For this study, a middle-aged woman is selected as the subject figure and one-piece is selected as the experimental clothes item. In real clothing, I conducted the wearing evaluation for experts and the subject figure. And In the virtual clothing, I conducted the wearing evaluation with i-Designer using 3D virtual clothing on simulation program. There are some differences between the data from body scanning and the real body size. In the custom-tailored clothing market in which the fitness is important, the research which measures the more exact data is needed. And in the case of complicate design, the functions which measure the activity and the fitness variously and correct the parts of curves are needed. This study experiments the availability of application of 3D Virtual Clothing System in custom-tailored clothing market by selecting one-piece as the experimental clothes item. So the follow-up studies for the other designs and fabrics are needed. Also, if the studies for checking the clothes pressure, the amount of composure, the space between skin and clothing when the virtual model wearing clothes is walking or shaking his arms are proceeding, then 3D virtual clothing System is applicable in custom-tailored clothing market. But there are some restrictions and lack of education in virtual clothing System yet, and it makes hard for workers in clothing market to use it in real production. However, 3D virtual clothing System will be practical in real market if there would be more research on its usability and practicality, and workers in clothing market can be easily educated on techniques of 3D virtual clothing system.

This study comprehensively analyzes previous research comparing the similarities between 3D virtual and actual fittings, and identifies the current usage and limitations of virtual fitting programs. The findings reveal that, in most cases, 3D virtual fittings are not perfect substitutes for actual fittings. To address these limitations, this research focuses on the Hohenstein fitting test and BP-ANNs-based garment fit evaluation method, which incorporate various parameters, such as the correlation between wearers and garments, garment pressure, and ease, thus providing objective data, such as data acquired that can enhance subjective evaluations. By integrating such objective assessments, the study suggests potential improvements in virtual fitting accuracy. This research is expected to provide foundational data necessary for the development of a consumer virtual fitting systems alongside advancements in 3D virtual fitting technology.
