This study presents an efficient clothes-sizing system for those experiencing obesity in old age with the aim of revitalizing the clothing industry for older obese people. The study targets 249 obese men aged 60 to 85 who satisfy a Rohrer index score of 1.6 or higher and a BMI (body mass index) of 25 or higher. Elderly obese males showed more obesity in the body based on the waist. In particular, those in their 60s were the most obese, and after reaching their 70s, characteristics of old age in which the stature was reduced and the limbs were tapered were shown. The clothes-sizing system was set to 5cm in stature, 5cm and 3cm in chest girth, 2cm in waist girth (omphalion), and 2cm in hip girth according to the KS standards. Through the two-way distribution of each section, the name of the section with a high distribution was given. Casual tops were selected from eight sizes, ranging from 155 to 170cm in stature and 95 to 105cm in chest girth. Suit top sizes were selected from eight sizes, ranging from 160 to 170cm in stature and 94 to 103cm in chest girth. Bottoms suggested 10 sizes distributed between 90 and 100cm in waist girth (omphalion) and 92 and 98cm in hip girth. According to the KS standards, the detailed size was divided into the basic part and the reference part.

In this study, the sizing systems of 40 unisex sweatshirt brands were analyzed to collect the size information needed to produce unisex clothing. Each size specification was compared with the body size distribution and percentiles of men and women aged 18 to 29. Depending on the brand, unisex sweatshirt sizes ranged from 1 to 8. Despite being unisex apparel, three brands offered only one or two sizes. Out of the brands surveyed, 50% were found to offer four or five sizes. Out of the 40 brands, 25 used letters such as "S," "M," and "L" to indicate the size designation. More than 92.5% of the brands included M and L, and the sizing system tended to focus on larger sizes such as XL and 2XL rather than smaller sizes such as XS and S. The size specifications of shoulder width, chest circumference, sleeve length, and total length were compared with the body size distribution and percentiles of men and women aged 18 to 29. The distribution of each size specification mostly appeared in a section larger than the men's body size. The size specifications of unisex sweatshirts were set close to or larger than men's sizes and hardly represented women's sizes. To increase consumer satisfaction with unisex clothing, establishing a size standard that could accurately reflect the body size distribution of men and women was found to be imperative. Such a size standard could also help each brand specify or diversify its target and differentiate itself with other brands.

This study suggests a detailed apparel sizing system for brands that target elderly men between the ages of 60 to 79 by studying body type differences of the age group based on data from 'The $5^{th}$ Korean Anthropometric survey'. Compared to middle aged men, elderly men body measurements appear to be smaller except in the midriff area, such as the natural waist circumference, waist circumference (omphalion), waist depth and waist depth (omphalion). The size chart in the study was established according to the KS size chart system with a size jump of 5cm in height, 5cm and 3cm in chest circumference, 2cm in waist circumference (omphalion) and 2cm in hip circumference. A total of 8 sizes were established with heights between 160cm and 170cm and chest measurements between 85cm to 100cm for casual tops. For suit tops, a total of 11 sizes were established with heights between 160cm and 170cm and chest measurements between 88cm to 100cm. For bottoms, detailed sizes were suggested by dividing basic and reference areas with 13 sizes between 84cm to 94cm in the waist circumference (omphalion) and between 90cm to 98cm in the hip circumference.

Most apparel products have national standards for sizing; however, for gloves, national sizing standards have not yet been established. This study aims to analyze children's hand dimensions and propose a size specification for children's gloves that shows children's hand-related size information. Among the 3D measurements of sixth Size Korea Project, the measurement data of 19 dimensions related to the hands of 1,057 boys and girls aged 7-13 years old were analyzed. The distribution and growth trend of hand measurements for boys and girls demonstrated considerable mean differences and distribution trends by gender and age as per hand dimensions, which leads to the conclusion that it is necessary to show these results in the children's glove design. Based on these results, the cross-distribution maps of children's hand length and hand circumference were drafted; furthermore, the distribution relationship with an adult hand size was identified. Based on the distribution of hand sizes, the distribution of adult hand sizes overlapped with children's hand sizes was verified, and children's glove size specifications were presented. The results can be used as useful data such as measures for setting the size range and sizing system for children's gloves.

This thesis was conducted with the purpose of proposing a systematic and comprehensive system for women's upper garment sizes so that the satisfaction level of women purchasing the upper garment products in Internet shopping malls is enhanced. To achieve this, this study first conducted a survey of women from the ages of 18 to 39 and attempted to discover consumer satisfaction levels and preferences of the clothing product sizing system of Internet shopping malls. While keeping track of the global distribution environment, an optimal clothing sizing system for Korean women that fit recent changes in their body shapes was proposed. The results of this study are as follows. First, A result of studying the satisfaction levels and preferences of consumer's purchase experience and the sizing system showed that 48.6% of the total respondents were dissatisfied with the current sizing system. Second, based on the research of the size classification system of domestic and foreign upper garment for women, unlike domestic Internet shopping malls, overseas generally offer several size classifications. Third, results of studies 1 and 2 was used to propose an optimal clothing products sizing system method. Also, the body and product sizes and the measurement methods should be offered together. In summary of all these results, by establishing globally compatible sizing system, consumers are able to recognize their sizes on their own and by doing this, it will lower perceived risk of the consumers at the time of a Internet shopping mall purchase, and this will raise their level of satisfaction while making purchases.

The purpose of this study was to analyze men's body sizes in order to develop men's garment sizing system. This study was based on the anthropometric measurements called Size-Korea, which was surveyed in year 2003 and 2004. The male subjects of the survey were 3215, who were from 18 to 69 years old. In the results, each age group had the statistically different mean of height from one another, which was inverse proportion to age. Analyzing with the height index values, Fifties had the biggest values in bust, waist and hip circumferences while Thirties had the biggest values when the circumferences were analyzed by its original measurements. Therefore, the consumers who wanted bigger sizes were Fifties instead of Thirties or Forties in case they had the same height. For the past 5 years, bust, waist, hip and waist-height were obviously increased and this phenomenon was remarkable at Twenties. The results of Correlation analysis showed that height, bust, waist, neck circumference were the key dimensions for the apparel sizing system.

As the population of overweight and obese children is rising rapidly around the world, there are many researches on purchasing and wearing children's clothing and optimal sizes, but researches on obese children are still inadequate. This study was carried out on 192 obese children over 75% in BMI. The purpose of the study was to set up the optimal interval of sizing system using the loss function which would be a guide for obese children for selecting ready to wear of suitable size. Introducing a loss function, which reflects how much the purchasing desire changes according to the difference, we formulate the problem and suggest a procedure to determine the optimal standard sizes minimizing the loss. These results were as follows ; In size chart of top's, 4 sizes had been determined by a loss function, had covered more than 91.1% of all subjects. In size chart of bottom's, 5 sizes had been determined by a loss function, had covered more than 87.0% of all subjects.

Body sizing of has been recognized as an important element affecting the degree of customer satisfaction in the apparel industry. Recent developments in IT technologies have enabled more studies in custom-made apparel systems that comply with the diverse demands from customers in many countries. Diverse methods to obtain personal physical size are being studied. This study estimates the accuracy by developing the system in which the data of length and girth can be calculated through changing a modeling by comparing the data with circular 3-dimensional physical configuration data. This information was computed from the process (such as the conversion to a standardize image) which utilizes the image capture of 2-dimensional three sides (front, side, and rear), contour tracing, and key-node selection and by realizing it in the real world.

This study was carried out on 132 obese women who satisfied both of conditions for obesity: equal to or over 1.6 in Rohrer index and 90 in bust girth. The purpose of the study was to set up a sizing system using the loss function which would be a guide for obese women to select ready-to-wear of suitable size. The results were as follows. 1) In the sizing system for large size apparel industry, each company has 4 to 7 sizes that differ in their content and number. Producing only 5 sizes was trying to minimize the producti on expenses. 2) The sizing system according to the loss function was the follwings. The height was 3: 149, 154.5 and 161 cm. The bust girth was 5:96.5, 100.5, 104, 107.5, 112 cm. The hip girth was 5: 95, 99, 102.5, 105.5, 110 cm. 3) In comparing the cover ratio of the newly suggested sizing system for obese women's garment with that of the Korea Sizing system for women's garment, the former was founded to have the greater cover ratio.

The purpose of this study was to classify size specifications of Korean adult male for the men's ready·made garments, especially jacket and dress shirts. Concept of the comfort and fitness has become a major concern in the basic function of the ready-made garments. Data were collected by the real anthropometric measurement and by the photographic sources. Sample size was 1.290 subjects as the sample and their age range was from 19 to 54 pean old by the stratified sampling method. 66 variables from the direct anthropometric data in total were applied to analyze. ANOVA in SAS package was applied to the data and the expected frequency distribution of 10.000 men was calculated by the extraction of density function. Control dimensions for jacket and dress shirts has been designated by Bcorean Apparel Sizing System (KS-K). Therefore this study was performed to classify size specifications by the control dimensions and at the same interval of KS-K. The drop values of 15, 12 and 9 has the high coverage rate of 22.1%, 21.0% and 18.8% respectively and are composed of the majority of 61.9% of the subjects. According to the drop values, size specifications and distribution of control and reference dimensions are predicted. About 65.75% of the expected frequency distribution without stature were covered by 19 size specification.
