This study aimed to develop appropriate jeans patterns for men in their twenties. The study discovered designs and materials that were most commonly used by investigating preferred jeans brands for men in their twenties, and among them three brands were selected. The study carried out a fitting assessment aimed at research subjects who had the average body type of men in their twenties and who wore jeans of the selected brands. Then, the study designed research patterns by taking as a basic pattern the patterns of the company who received the highest score and modifying any part that revealed a problem. After making the research jeans in twice, a fitting adequacy assessment was undertaken in order to identify any difference between the existing jeans and the research jeans. As a result of the appearance assessment, the problems shown in appearance overall was confirmed to be improved as it received a higher assessment compared with the existing jeans overall. As a result of the fitting assessment, the study collected the assessment results of waist measurement, hip circumference, thigh circumference, and fit of back central line laid slope ease. Based on the result, the study confirmed the parts to be modified and proposed slim fit jeans patterns in consideration of the body type characteristics of men in their twenties.

The purpose of this study is to develop a slim-fit jeans pattern that is suitable for the lower body of upper grade elementary school girls, who are beginning to show gender differences in body shape. Four age groups of two years each were considered for girls 7 to 14 years old. The mean and standard deviation of body measurements were calculated for each age group to analyze body shape variation, and hence the body characteristics of upper grade elementary school girls were identified. The high-frequency measurements of stature-waist circumference and waist circumference-hip circumference combinations were analyzed. In order to determine the size of each part of the jeans pattern and derive the drafting formula, the pattern sizes of brand A jeans, which had received a high score in the evaluation for ready-to-wear jeans(Kim & Lee, 2020), were used as the base criteria. In addition, the body sizes observed and calculated in the study were applied. Additionally, the requirements for better fit of ready-to-wear jeans, found in the survey on jeans wearing conditions and size dissatisfaction(Kim & Lee, 2019), were taken into consideration. Based on this research, a model set of jeans was prepared with the pattern developed and its fit evaluation was conducted. Thus, a slim-fit jeans pattern suitable for the lower body of upper grade elementary school girls was finalized. The pattern proposed in this study has excellent appearance and motion functionality, and is expected to contribute to reduce the fit dissatisfaction.

This study is based on anthropometric data from the 7th Size Korea, we selected five subjects with measurements similar to average women in their twenties. The subjects participated in adaptability assessments and appearance assessments of skinny jeans produced by 8 selected brands, to identify the pattern and measurements characteristics of jeans assessed to be superior in appearance and movement adaptability. The results of this study were as follows. First, according to the results of appearance assessment made by the specialist group, B brand earned the highest assessment in response to questions regarding if 'there is an appropriate amount of ease in the crotch area' on the front side and 'an appropriate amount of ease in the hip circumference area' on the back side. Based on the above results, Synthesizing the survey results and the appearance assessment and movement adaptability assessment results, we suggest that when drafting the pattern for the standard size of waist measurement 27 inches (67cm), the hip circumference should be given an appropriate amount of ease, of around -6.6cm (-7.2%). The thigh circumference should be set with an appropriate amount of ease, which is -5.3cm (-9.4%).

This study focusses pattern draft and grading of jeans for women in their 20s, who consume jeans the most. Pattern was drafted based on existing patterns collected from companies. It is different from the existing educational patterns. It suggests new sizing system for twenties referring to sizes used companies and grading rule and method. he results were as follows; 1. Companies manufacture 2-8 sizes and they referred to the Korean Industrial Standards, KS K 0051, for their sizing system. 2. Drawing method for Pattern of the study had following measurements for each part: in the case of waist circumference, front part was W/4+1.5cm, back part was W14+2cm, front hip circumference was H/4-1.5cm, crotch line was the crotch length (practical measurement), hip circumference was (upper crotch line length)/5+0.5cm, front crotch part was 2.7cm, back crotch part was W/5+2.7cm, knee height was (the length of leg)/2+6cm and the circumference of knee and the tip of pants were 40cm. Through the wearing test on the subject of twenties, researched pattern received higher ratings, especially in appearance than the existing pattern. 3. 5 sizes system was made referred to the sizing system of companies and National Anthropometric Survey of Korean in 1997 Grading rule for 12 grading points of front part and 13 grading points of back part was suggested. Results of wearing test on the graded patterns showed high ratings similar to standard size.

This study identifies methods to design patterns for jeans that are suitable for women in their twenties. Five patterns suggested by previous researchers were used to draw the same size of jeans (waist 67 and hip 91). The author compared and analyzed the measurements and shapes of the patterns, ranging from waist to crotch. Samples were produced based on these patterns and then tests were conducted to observe the dynamic functions and exteriors of the samples. The dynamic functions observed in this study include walking, ascending stairs, descending stairs and sitting on chairs. The results of the current study are as follow. The best evaluated pattern in terms of exteriors is the one where the hips and thighs are tightest compared to other patterns and where the back part is wider than the front part. This pattern also received high evaluations in dynamic functions due to comfort when walking. Regarding ascending or descending stairs, the tests found that all its parts (except the front crotch) are more comfortable than those of any other patterns. All these results show that a comfortable fit and easy movement is possible when the crotch width of the back is broader than the hip width so that the hips are comfortably supported.

The purpose of this study was to present a making method of jeans pattern with high fitness after deriving the appropriate shrinkage rate by material and washing process. According to the result of the exterior evaluation of test jeans, all 6 jeans were rated high with scores close to 3.5. Following the evaluation of satisfaction of usage by physical movement, the highest ranking was in the order of walking with normal steps, back bending $90^{\circ}$, chair sitting, climbing stairs and squatting. The shrinkage rate by physical area showed the highest score in the order of pants length, waist circumference, thigh circumference, knee circumference, hem circumference, hips circumference. In addition, the shrinkage rate was higher in warp direction than weft direction after washing finishing. As for the result of addition and reduction of pattern measurements by parts of jeans, waist circumference was $3.1{\sim}5.1cm$, hips circumference was $-1.2{\sim}4.2cm$, thigh circumference was $-0.9{\sim}3.1cm$ and pants length was $3.4{\sim}6.1cm$. That is, this results showed a wide range of addition and reduction according to material and washing finishing.

This study collected the basic data required to develop a slim-fit jeans pattern for upper grade elementary school girls. First, a fit evaluation was made by selecting five slim-fit jeans of ready-to-wear brands. Subjects were four girls aged 11-12 with an average body size that evaluated the appearance and motion functionality of five brands of jeans. Five experts also evaluated their appearance. Second, pattern sizes were analyzed and compared with the average size of upper grade elementary school girls by measuring the pattern sizes of five brands jeans. As a result, Brand A received a high score in appearance and motion functionality. Brand E scored high with Brand A in appearance, while Brand E had the lowest score in motion functionality. For most of the five brand jeans, (+) ease was added to include a wide range of body sizes for upper grade elementary school girls, but the hip circumference, thigh circumference, and knee circumference of Brand E jeans were smaller than the average size of girls. The (-) ease was applied to make the figure look slim, which resulted in a high appearance score. However, since Brand E received a low score in the motion functionality, it could be seen that the (-) ease was not suitable for subjects although the material was stretchable. The result of this study will be used to develop a slim-fit jeans pattern suitable for upper grade elementary school girls.

This study provides information on how to improve the wearing sensation and the fit of slim-fit jeans through an analysis of actual wearing conditions and dissatisfaction. The study is based on a questionnaire survey. A survey was conducted on 296 women in their 20s living in Korea to analyze wearing dissatisfaction with slim-fit jeans. The study used descriptive statistics for analysis using SPSS Statistics Ver.23. Surveys on the actual situation of wearing jeans and level of dissatisfaction indicated that most women in their 20s mainly wore slim-fit jeans and were aware of the size of their jeans. Most tended to double-check the size of the jeans, indicating that the inaccurate sizing system of slim-fit jeans caused confusion for consumers. In addition, the results of the survey on the most considered parts of the body when consumers buy jeans are waist, thigh and leg length. They insisted that their waists were thin and their thighs were thicker than their waists; so their pants would not fit and they were obese. There is a problem between waist size and thigh size; therefore, it is necessary to develop new patterns for slim-fit jeans with improved fit around the waist area that can improve the negative results of surveys on the level of dissatisfaction, indicating discomfort in the waist, belly, and thigh areas while wearing slim-fit jeans.
