The 3D virtual fitting system is a new and very efficient system replacing real fitting in apparel industry and on-line shopping. It is a win-win system for both of consumer and manufacturer which not only reduces design and production time but also resolves consumer's complaints by checking the wearing image beforehand. It is a must-have item in the future. The purpose of this study is to analyze sizing menu, terms, and current status and to figure out problems of avatar sizing programs which substitute human bodies in virtual fitting. We chose three existing outstanding programs in domestic and global market, compared and analyzed the program, manual, and terms that are used in avatar sizing, and investigated the strengths, weaknesses, problems of options and terms and finally suggested an alternative terms. The revealed problems are as follows: each program supports various avatars ranging from male to female, from child to adult, and from oriental style to western style. The image of the avatar could be changed through the options for hair style, shoes and accessories. But we found out some problems. The avatar body types are far from actual human body types, avatar sizing menus and item terms are different from program to program, and terms not yet standardized. Cooperative efforts of industry and academy on standardization of sizing menus and terms should be emphasized for the virtual fitting system to be widely used like the other computer graphic programs or word editors.

The manufacturer first identifies a target market before developing a sizing chart. A target market is specific for age or figure type. The purpose of this study is to evaluate the suitability of sizing system of women's apparel brand in Korea. For this purpose, the characteristics of the manufacture's sizing chart for jacket and skirt/pants were analyzed. For each brand, the target age of the brand and the age of consumers who preferred that bland were compared. The size charts collected from 27 women's apparel brands were analyzed and compared with Korean industrial standard sifting chart. The results of this study reviled that the body proportion in many manufacturer's sizing chart does not correspond to the body types in Korean industrial standard sizing chart. This trend was apparent for the short figure sizes made for women 155cm in height. There is a difference between the target age in brand concept and the age of consumer preferring to purchase that brand apparel. The age of fitting models usually does not correspond the customer's age. It was concluded that the age of target customer does not go well with the age of brand concept nor the fitting model age caused fit problem of the women's ready-made clothes.

This study investigated the usage and product conditions of clothing companies and online dummy companies for the development of fitting dummy for South Korean women's wear in their 50s and 60s. These women-targeted apparel companies mainly used nude-sized torso type and torso crotch type made of FRP material. The frequency of use of the dummies was high, while the user satisfaction was moderate. Users expressed dissatisfaction with the inaccurate reflection of the body shape according to the KS sizing system and the measurements such as the front and back intercye, upper arms, abdomen, crotch, and waist back length. Upon survey, 73.7% of the respondents answered that development of the dummy and the appropriate age for it is 50 to 54, and they preferred the torso crotch form. In the production of online dummy companies, the torso crotch type and torso type were most widely produced, and polyurethane, FRP, and recycled paper materials were used. The size of dummy was expressed in numerical type, and 6, 7, 8, 9, 10, 12, 14, 16, 18 and 44, 55, 66, 77, 88 were being produced. Even models of the same size had significant deviation, especially in the waist circumference. Also, there was no dummy reflecting 25%~75% center interval to the KS garment sizing standards of women in their 50s and 60s. Therefore, it is desperately necessary to develop a fitting dummy for KS clothing sizing system that reflect their body sizes and shapes.

The purpose of this study was to recognize of the sizing system and analyze the fitting on formal pants of the on-line shopping mall for plus-sized women. To pursue this purpose, the investigation of the sizing system was focused on 22 online companies. The formal pants of 7 companies was selected among them. And actual sizes were compared with the guidance sizes of goods. For the assessment about the fitting on formal pants of 7 online companies, these came to make on to 16 obese women with 'A' body shaped and 'O' body shaped. A data analysis used the SPSS 14.0 statistics program. To verify the difference, this study used the variance analysis and Duncan's test for the postmortem verification. The result was as follows. 1. All of 22 companies were using the symbol such as 88, 99, 100 and 110 in the present condition of sizing system. The information about products size was presenting the products size not to be the body size. the guidance sizes of products were different from actual sizes of 7 companies to be assorted. Therefore, the guidance sizes of goods could not accomplish the facility. 2. According to the fitting-tests by the sensory assessment, the obese women with 'A' body shaped, did the dissatisfaction at the items of the hip circumference, abdominal region, crotch deep and pants length. The obese women with 'O' body shaped, did the dissatisfaction at the the items of crotch deep and pants length.

This study aims to design a new sizing system for hygienic masks to protect against COVID-19-related respiratory disorders. The product sizes were collected from 70 commercially available hygienic masks, and 18 head measurements were obtained from the three-dimensional (3D) scan data of 2,048 men and women aged 20 to 69 years from the 6th Size Korea Survey. The statistical analysis was performed using the IBM Statistical Package for the Social Sciences (SPSS) 28.0 program. The "bitragion-subnasale arc" and "menton-sellion length" were chosen as the key body dimensions for the hygienic mask sizing system. The linear regressions with 18 3D head measurements were analyzed, and it was determined that the key body dimensions were useful for statistically predicting other 3D head measurements related to hygienic masks. A new sizing system was proposed for two types of masks, "masks with a tight fit" and "masks with a loose fit," taking into account the existing Korean Industrial Standards (KS) and the shortcomings of the sizes of hygienic masks on the market. The sizing system for tight-fitting masks consisted of the key body dimensions, with their sizes indicated by a pair of numbers. The sizing system for loose-fitting masks consisted solely of the bitragion-subnasale arc, with their sizes denoted by letters such as S, M, and L (denoting small, medium, and large, respectively). Future studies should consider this mask sizing system for different age groups, such as children and adolescents.

Menswear body types are often labeled on garments (to indicate how the garments are designed to fit) with indicators of a size category such as regular, portly, and stout, athletic, or big and tall. A drop (relationships between the chest and waist girths) is related to the fit of a tailored suit. However, current standards are not designed for various drops or body types. There is not enough information of categorizing men's body shapes for the apparel sizing systems. In this article, a set of men's data from SizeUSA sizing survey was analyzed to investigate men's body shapes and drops. Factor analysis and a cluster analysis method were used to categorize men's body shapes. In the results, twenty-five variables were selected through the factor analysis and found four factors: girth factor, height factor, torso girth factor, and slope degree factor. According to the factor and cluster analysis, various body shapes were found: Slim Shape (SS - tall ectomorphy), Heavy Shape (HS - athletic, big & tall, endomorphy and mesomorphy), Slant Inverted Triangle Shape (SITS - regular, slight ectomorphy and slight mesomorphy weight range from normal to slightly overweight), Short Round Top Shape (SRTS - portly and stout, endomorphy). Body shapes were related to fitting categories. SS and HS were related to big & tall fitting category. SITS was related to regular. SRTS was related to portly and stout. Shape 1 (31%) and Shape 2 (26%) were related to current big & tall category. Shape 3 (34%) were related to regular. Shape 4 (9%) were in portly and stout category. ASTM D 6240 standard was the only available standard that presented a regular fitting category. Various drops were found within a same chest size group; however, this study revealed great variances of drops by body shape.

The purpose of the study is to survey the current state of tween generation boys' clothing-wearing, to identify problems in the current apparel sizing system, and to contribute to the improvement of the fitness of ready-made clothes. 1. According to the result of surveying the current state of clothing-wearing, boys prefer casual wear and, as they grow old, they tend to purchase clothes alone or in company with their friends. In addition, they use mainly easy casual wear or sports wear stores. They appear to be highly dissatisfied with price and size and think that the fitting of coats, pants and jackets is poor. Moreover, they complain about sizes such as waist circumference, pants length and upper-arm circumference. 2. According to the result of comparing apparel sizing system with body measurements, the waist circumference and hip circumference of young casual wear are fit to the large size of body at the age of 12 and the over-average size of body at the age of 13 and 14, but its bust circumference is fit only to the extra-large size of body at the age of 13 and 14. Such results come from differences in body shape between adults and adolescents. Although adolescents' body size has been enlarged, their body line is still immature and, accordingly, their drop-value is smaller than that of adults, which appears to cause adolescents to be highly dissatisfied with fitting.

This study provides basic guidelines to enrich lecture content and teaching methods for university lecturers about basic clothing construction (flat pattern making). The survey was conducted from October $13^{th}$ to December $20^{th}$ 2010 by mail and e-mail on 96 selected clothing departments in Korean universities to investigate the content, method and condition of the course of basic pattern making. A total of 63.3% of survey respondents were PhD graduates, 80 percent majored 'Apparel Science and Technology', average of total teaching experience was 12.84 years and 40 percent had studied abroad. The surveyed universities were 4 year universities (70%), 2-3 year tenure colleges (27%), and Cyber Universities (3%). The average number of students in a class was 28.08 and the lab space and equipment was evaluated positively only when the number of students was 20 or less. The type of measurements for basic pattern drafting were 'individual student's sizes' (62%), 'ready-made clothes sizing system' (25%), 'professor's experiential sizes' (5%), 'dress form sizes' (3%). In addition, the percentage of using 'ready-made clothes sizing system' increased 13% over the previous study (Lee, 2000). At a basic pattern drafting stage, 'the error of body measurements' in the case of using individual student's sizes, 'the poor results of fitting for students who deviate from standard body size' in the case of using ready-made clothes sizing system, 'the lack of education about fitting' in the case of using dress form sizes had been pointed out as shortcomings. A total of 66% of survey respondents carried out muslin fitting; however, a lack of students and teacher feedback about fitting & alteration of paper patterns remained a problem.

The pantyhose is a close-fitting garment, and consumers are highly sensitive to any progress made in fitting the garment to their lower body and increasing comfort. However, the pantyhose manufactured in Korea are only one-sized. The purpose of this study is to suggest a sizing system for pantyhose. The results of this study are as follows: 1. As a results of questions regarding the sizing system of pantyhose, 88.2% of people who responded to our questionnaire preferred multi-sized pantyhose. In particular, larger women opposed to thin women expressed some dissatisfaction in the length and the width of the pantyhose. In addition, most of women preferred an indication of the sizing system and the body size of the control dimension (body mass and height). 2. The 13 species of pantyhose that were manufactured abroad are of all sizes, and only one type of pantyhose is one-sized. However, most domestic pantyhose except one, are one-sized. 3. As a result of the experiment, the spandex content in pantyhose was approximately 12∼18%. Moreover, the elongation rate was approximately 200-370%, which differed according to the features of the material. The stretch size of the pantyhose had varies greatly, add has not yet been standardized. 4. The methods for indicating the pantyhose size in this study are the square method and the stair method. The characteristics of the square method are simple, but the coverage is relatively low. The characteristic of the stair method are so complicated that older women have a low preference for this method. However, the coverage rate is high.
