This study analyzes the body shapes of lower-body obese female adolescents and proposes a slacks pattern suitable for their body type. Lower-body obesity is a prevalent type of teenage obesity, and our proposals aim to improve consumer satisfaction in ready-to-wear clothes across this demographic. We first observe characteristics of obese lower bodies, noting significantly above-average thigh and hip circumference. These figures indicate a high degree of curvature in obese lower bodies, along with a large drop value. Leveraging this data, we develop a novel slacks pattern using 3D avatars in a virtual simulation system. The formulas for the main areas of the pattern are as follows: front waist girth W/4+0.75cm+0.5cm, back waist girth W/4+0.5cm– 0.5cm, front hip girth H/4+1.25cm–0.5cm, back hip girth H/4+2cm+0.5cm, front crotch extension H/16+0.5cm, back crotch extension H/8+1cm. Results from appearance evaluations show that this pattern minimizes strain rate on the waist and hips, and its average score is significantly higher than that of an alternative pattern that was also evaluated. The minimized strain rate and high average score indicate that our pattern assigns a sufficient amount of space to the appropriate areas. Based on these results, we expect our research to inform slacks pattern development and production for obese consumers of all types.

This study seeks to increase the satisfaction of elderly men when purchasing and wearing ready-to-wear clothes by designing a slacks pattern suitable for their body type, which is determined by analyzing their lower bodies using virtual avatars and 3D virtual simulation system. The study found the following. First, based on virtual visualization of the comparison slacks pattern, the waistline position was consistently the lowest scored question among the evaluation survey items. Interpretation of this dissatisfaction suggests that, because the front waistline falls below the abdomen, the lower body, and especially the abdominal shape, is unpleasantly emphasized. Second, by using a virtual simulation system, the study developed a new slacks pattern that considered the concerns of elderly men. The primary measurement changes were as follows: front waist girth W/4+1.5cm+0.5cm, back waist girth W/4+1.5cm–0.5cm, front hip girth H/4+2.5cm–0.5cm, back hip girth H/4+2.5cm+0.5cm. Third, the new slacks pattern’s appearance was evaluated more highly than the comparison pattern, confirming the new pattern’s appropriateness for elderly men. This study demonstrates how slacks and other clothing patterns designed in a 3D virtual garment simulator can be used to design more appealing clothing for elderly men, increasing the satisfaction of wearing ready-made clothes at older ages.

The purpose of this study was to develop slacks patterns for obese-schoolgirls aged 10~12 by using a 3D virtual garment simulation system. The criteria for subjects in this study were girls who had a BMI of over 25kg/m2. A total of 155 schoolgirls who met these criteria were enrolled. The results were as follows: First, by using 3D virtual garment simulation, a new slacks pattern considerate of obese-schoolgirls was developed. The basic numerical formulae were as follows: Front and back hip girth of H/4－0.5+1 and H/4+0.5+1.5, front waist girth of W/4+1+0.5, back waist girth of W/4+2+0.5, front crotch extension of H/16－0.5, back crotch extension of H/8－0.5, front dart amount of 1, and back dart amount of 2. Second, according to the new slacks pattern appearance evaluation, the new slacks pattern scored more highly than the existing pattern for silhouette and ease amount, confirming that the new slacks pattern is appropriate for obese-schoolgirls. Additionally, the new slacks pattern was evaluated allowing for the proper space length of the waist, abdomen and hips. This study is expected to serve as important basic data for ensuing studies that may utilize a 3D virtual garment simulation system with 2D patterns and for future 3D pattern production program development.

The purpose of this study was to develop slacks patterns for middle-aged abdomen-obese adult males by using the 3D virtual-twin and virtual-garment simulation system. The criteria for subjects in this study were males who had over 25kg/m2 of BMI, over 90cm of waist, and over 0.90 of WHR. A total of 211 adult males who met these criteria were enrolled. The results were as follows: first, a new slacks pattern considerate of abdomen-obese men was development. The basic numerical formula were as follows: front and back hip girth H/4+3.5, front waist girth W/4+1+0.5, back waist girth W/4+1－0.5, front crotch extension H/16, back crotch extension H/8－0.5, front pleats amount 2.7, and back dart amount 1.5. Second, according to the results of the new slacks patterns appearance evaluation, the new slacks pattern scored more highly than the existing pattern in silhouette and ease amount, confirming that the new slacks pattern is appropriate for the abdomen-obese men. Also, the new slacks pattern was evaluated allowing proper space length of waist, abdomen and hip. Virtual models of production through data from a 3D body scan, pattern draft and virtual garment digital program were applied to a prototypic design method in order to enhance the fitness of ready-made garments. The use of the virtual twin made it impossible to comprehend the appearances and ease correspondent to motions. In order to evaluate wearing fitness, therefore, the system should be improved so as to change arm positions and perform various motions.

The purpose of this study was to compare and analyze two original forms of slacks for thesis to extract outward appearance of design original form applying design measures of the above through diverse research methods. The results of this study are as follow: In original form F, the original form of slacks sloper suitable to elderly women 65～69 years old was W/4+3.5+0.5cm in the front/back circumference of waist, H/4cm in the front/back circumference of hip, (H/4+1+3.8)/2cm in the position of centerline, 19cm in actual measurement value of hip length, 25cm in actual measurement value of crotch depth, (knee crotch circumference～bottom line)/2+10cm and 90 (side waist dot～ lateral malleolus length)cm in actual measurement. front dart position was 1/3 and 2/3 of front waist centerline and back dart position was 1/3 and 2/3 of back waist circumference. It was suggested that front dart quantity (length) was 3.5(11)cm, back dart quantity 3.4 (10.2)cm, side waist up quantity 0.7cm, back down quantity 1.5cm, front crotch width (H/4+1)/4-1cm, back crotch width (H/4+1)/4+4, front knee width 21.8cm, back knee width 24.4cm, front pant leg 20.8cm, and back pant leg 23.4cm.

This study is aimed at developing low waist slacks pattern with high satisfaction measurements and beauty for the tween generation girls. For this study, the research method was as follows. By extracting and analyzing industrial and educational slacks pattern, beautiful and motion-suitable slacks pattern will be created. This study presents the ideal slacks pattern that has great fit to tween generation girls by comparing and analyzing the previous 2 slacks pattern studies and the real clothing test. The constructed pattern in the 1st step was modified and adjusted from the best industrial patterns' the location of waist line, waist line gradient, rear waist bottom crotch, hip bottom crotch, dart length, the ease of hip girth, the fitness of rear bottom crotch line which were not well-estimated. The 2nd step was appearance and movement test based on the 1st study. In The 3rd step, the 2nd step was chosen as the final slacks study pattern for its superior appearance & movement satisfaction comparing with other patterns.

The purposes of this study were to examine the slacks purchases and wearing satisfaction among old-aged women who were highly dissatisfied with their bodies and fit due to physical changes and to provide some basic data needed to develop slacks patterns to meet their needs. A survey was taken among 223 old-aged women aged 60～79 living in Seoul. Using the SPSS 12.0 program, the collected data were analyzed in descriptive statistics, t-test, and crosstab. The result were as follows: the most used place for them to shop slacks was a market(including the Dongdaemun and Namdaemun market), which was followed by a department store and a discount store in the order. As for their preference for slacks according to age, those who were in their sixties most preferred straight-line slacks, while those who were in their seventies semistraight-type slacks. As for fit for each body part according to age, there were significant differences only in crotch length. Those who were in their seventies were more dissatisfied with crotch length than those who were in their sixties, feeling that crotch length was short. As for their experiences of repair after purchasing a pair of slacks, 82.5% said they had such an experience. Most of the repairs with length, waist and slacks width involved in size reduction.
