The purpose of the study is to develop the basic pattern of casual jacket for men aged between 25 and 34. Compared to the tailored jackets, casual jackets are designed much more diverse form depending on the target customer, price range and moreover fashion trend. Therefore in order to reduce the cost and time of developing new style, pattern draft from the basic pattern is better approach rather than develop each style form the measurements every time. For men's casual jacket pattern draft, the basic pattern of fit and comfort was developed through following research procedures. 173 men were surveyed about their habit of buying and wearing of casual jackets. MDs and pattern designers of 10 casual wear brands for men were interviewed. As a starting point, 3 different basic patterns were selected. 2 patterns were from the 2 interviewed brands and the last one was the pattern of ESMOD. The 3 patterns were studied by means of comparing measurements and general styling. As a results it was found that the pattern of S brand is featuring I silhouette, the pattern of K brand is featuring H silhouette and the pattern of ESMOD is featuring Y silhouette. The results of wearing test showed that the pattern of S brand is the best among the three. They were to add ease around the chest line and waist line, to relocate the waist line and the break point, to increase the jacket length and upper arm width. The improved pattern was made of polyester for the wearing test. The wearing test showed developed pattern was improved significantly. To verify the use of developed basic pattern, two buttoned single jacket was made.

In this study, we have developed the ergonomic pattern from the 3D human body reflecting cycling posture and extensibility of the stretch fabrics. Adjusting pressure level in the construction of athlete's tight-fitting stretch garments by reducing the original pattern is a challenging subject, which influence on the performance of the wearer directly. Therefore, in this study, relationships between the reduction rates of the 2D pattern obtained from the 3D human scan and resultant clothing pressure were explored to improve the fit and pressure exerted by reduced clothing pattern. Subjective wear sensations of the experimental garments were rated using a seven-point Likert scale on two consecutive days. While wearing the garments, subjects were asked to take five different postures including waist flexion, sitting and others. A Likert-type scale was used for the evaluation, with 7 points indicating the best fit in tight-fitting pants. Comparing 2/3T-pattern with T-pattern, the latter was superior to 2/3T-pattern in terms of adhere well to the waist and hip area in the 0.032 significance level. T-pattern was superior to 2/3T-pattern in terms of fitting and wear comfort. As results, the pattern obtained from the flexed body reflecting cycling posture already included the contraction and extension of the skin while cycling posture, so that the extra ease for movement and good fit was not need to be considered. The optimized reduction rates were determined with the proposed reduction rate, the resultant pressure range was within the range of $0.5{\sim}3.0gf/cm^2$ at eight locations on the body except front waist band and thigh band.

The purpose of this study was to suggest torso patterns that fit the three main body shapes of elderly obese women. To reduce time, costs, and also the trial and error needed to make patterns, the CLO program for 3D test wear was employed. Three virtual models for aged obese women were use, with the YUKA system used to produce torso patterns. 3D simulation of test wear and corrections was done to design optimal torso patterns. The results were as follows: First, for the three models of obese women's body shapes as realized by CLO 3D, Type 1 is lower-body obesity shapes, Type 2 is abdominal obesity shapes, and Type 3 is whole-body obesity shapes. Second, to design the study patterns, actual measurement values, back waist length and waist to hip length, were used. The armhole depth (B/4-1.5), front interscye (B/6+2.3), front neck width (B/12-0.5), front neck depth (B/12+0.5), front waist measurement (W/4+ 1.5+D), front hip measurement (H/4+2+0.5), and back hip measurement (H/4+3-0.5) were calculated using formulas. Third, according to the results of test-wearing the study patterns, reduced front neck width and depth improved the neck fit and reduced armhole depth bettered loose or plunging armhole girth and also reduced the sagging of bust c.. Also, tight sidesfrom aprotruded waist and abdomen improved with the increase of surpluses in the back waist and also back and front hip c. The exterior was enhanced by displacement of back and front darts, which distributed surpluses better.
