In modern society, there is a tendency to prioritize both fashion and comfort, with a preference for loose-fit clothing that enhances mobility. While darts may not be visibly present on the garment's exterior, their effects should be dispersed and incorporated into the design. However, there is a significant lack of systematic research on dartless patterns in the current state. Therefore, this study focuses on investigating dartless patterns used in loose-fit clothing tailored to the body measurements of women in their 20s. The objective of this research is to develop foundational dartless patterns that serve as a basis for diverse design possibilities in loose-fit clothing. To achieve this purpose, seven dartless patterns introduced in clothing construction references were selected for the production of experimental prototypes, which were then subjected to visual evaluations by a panel of experts. Based on the evaluation results, superior patterns were selected and they underwent modification and improvement to develop the research patterns. The developed research patterns were derived through the formulation of calculation formulas, and based on these formulas, garments were produced. Subsequently, a second round of visual evaluations was conducted by a panel of experts, and notable improvements were observed in most of the aspects assessed. However, it should be noted that this study was limited to women in their 20s it did not explore a wide range of fabrics. Therefore, further research is needed in the future.

Dressmaking is a high value-added sector of the fashion industry in which the individuality and skills of designers play a prominent role. The appropriate use of the draping and the flat pattern techniques in the dressmaking process also play an important part in perfecting the finished product. The purpose of this study was to improve the understanding of dress design and identify a pattern production technique to enhence efficiency in each of the three elements of the dress manufactureing process. For this purpose, analysis of the design of 1,389 wedding dress photographs published in Wedding 21, Korea's leading wedding magazine, during 2019 and 2020 was conducted. This analysis identified 15 bodice designs and 11 sleeve designs based on neckline and eight skirts based on silhouette which were ranked by frequency distribution. Patterns for the design of samples were then developed according to the highest combined frequency distribution of these three elements. Eight samples were finally produced to test the the efficiency of the patternmaking techniques empolyed and the selected designs. The findings from this study have practical applications, notably in improving the efficiency of pattern production techniques that will facilitate further growth in the dressmaking industry.

With recent advances in 3D scanning technology, three-dimensional (3D) patternmaking is becoming a powerful way to develop garments pattern. This technology is now applicable to the made to measure (MTM) system of both ordinary and tightly fitting garments. Although the pattern of fitted clothing has been developed using 3D human data, it is still interesting to develop cycling pants by considering while-cycling body posture and fabric elasticity. This study adopted the Garland's triangle simplification method in order to simplify data without distorting the original 3D scan. Next, the Runge-Kutta method (2C-AN program) was used to develop a 2D pattern from the triangular pixels in the 3D scanned data. The 3D scanned data of four male, university students aged from 21 to 25, was obtained using Whole body scanner (Model WB4, Cyberware, Inc., USA). Results showed the average error of measurement was $4.58cm^2$ (0.19%) for area and 0~0.61cm for the length between the 3D body scanned data and the 2D developed pattern data. This is an acceptable range of error for garment manufacture. Additionally, the 2D pattern developed, based on the 3D body scanned data, did not need ease for comfort or ease of movement when cycling. This study thus provides insights into how garment patterns may be developed for ergonomic comfort in certain special environments.

This study classified and analyzed the upper body types of 7-13 years old elementary school boys, using 3D data from the 6th Size Korea. The results of this study are as follows. Seven factors were extracted from the factorial analysis as an independent factor for a cluster analysis. The cluster analysis generated four body types. Type 1 has large ratio of front and back depth as well as circumference, with a front protrusion. In Type 2, the vertical value of upper torso is longer than average; in addition, its flatness is the largest and produces a thin body type. Type 3 has a smaller flatness in the bust, waist, abdomen and hip than other types, while also having the largest BMI. Type 4 is characterized by a greater shoulder angle than other types and its other factors are close to average. As a result of the logistic regression analysis, the prediction model used eight variables to generate and its accuracy is 88.679%. The classification of upper body types from this study can be used as basic data to improve patternmaking for each body type. The generated prediction model is also expected to be used as a method to help classify upper body types using the eight variables.

Recently, according to changes in fashion trends, the importance of stretch fabric stands out. A lot of studies on non-stretch woven fabrics have been made, but few studies on stretch fabrics has been made yet. Especially, the study on ease for the patterns, according to body types, of stretch has not been made at all. The purpose of this study was to make clear reduction ratio due to the stretch ratio and to find out the ease for the patterns of stretch skirt according to standard body type to improve the aesthetics and wearing satisfaction. Therefore, fundamental data for aesthetic and functional patternmaking of the stretch skirt can be suggested. The results from the study were as follows: 1. The results from the appearance test were as follows. For the ease on waist, W+0㎝ and W-1㎝ for standard body type were suggested for the best fit. For the ease on hip, H+2㎝ and H+0㎝ for standard body type were suggested for the best wearing best fit. 2. The results from wearing satisfaction test were as follows. W+0㎝, H+2㎝ for standard body type were suggested for the best wearing satisfaction. 3. Based on the results from the above tests, the pattern reduction ratios for stretch skirt were as follows: pattern reduction ratio 3.0∼4.6% of waist, 2.1∼4.3% of hip for standard body type were suggested for the appropriate reduction ratio for stretch skirt. 4. The result from this study for stretch skirt was as follows: For standard body type, W+0㎝, W-1㎝ for waist and H+2㎝, H+0㎝ for hip were appropriate for stretch skirt pattern.

The aim of the study is to propose ways to improve the break line fit of women's tailored collar vests by modifying the patternmaking process. The study explored the fit effects of experimental vests with a focus on 3 different breast sizes, A, B, and C cups. Women in the ages between 20 and 24 in South Korea were targeted. In order to carry out the objective, the study implemented separate girth measurements for the front and the back of the tailored collar vests, and also allocated different dart amounts on the lapel through the break line according to the different breast cup sizes. The study adopted a 5-point rating scale to perform evaluation of the different fit effects caused by the varying dart amounts given on the experimental vests' break lines. This evaluation was carried out by apparel pattern experts. The results derived from the study were as follows: first, the implementation of separate girth measurements provided originality to the study, as the application of different measurements for the waist back length and the neck shoulder point-to-breast point-to-waist line led to the front panels of the experimental vests having varying slack amounts. Second, break line dart was applied in three different amounts, 0.5, 1.0, and 1.5cm respectively according to A, B and C breast sizes, and as the dart amount increased, extra ease on the break lines was reduced. The dart was applied on the edge lines of the lapel and it was applied from a point which was 6cm above the breast point to the end of the princess line for all the breast cup sizes.

This study aims to suggest the proper neck-width of slim-fit jackets according to numbers of jacket buttons from an one-button jacket to a four button jacket for men in their 30's. The researchers carried out both an appearance evaluation and a movement functionality evaluation. When analyzing the appearance evaluation, there were meaningful differences. The one-button jacket showed a high score on the back-neck width of +2.4cm. The two-button jacket and the three button jacket showed a high score on the back-neck width of +1.4cm. The four-button jacket showed a high score on the back-neck width of +0.4cm. The result of movement functionality evaluation was not related to the appearance evaluation, and showed no meaningful difference. The one-button jacket and two button jacket showed high scores on the back-neck width of +2.4cm. The three button jacket showed a high score on the back-neck width of +1.4cm. The four-button jacket showed a high score on the back-neck width of +0.4cm. In analyzing both results, the study suggests that the proper front neck-width and that of the back-neck width of +2.4cm be for the one-button jacket, the back-neck width of +1.4cm be for the two-button jacket and the three-button jacket, while the back-neck width of +0.4cm be for the four-button jacket.

This study aims to examine the effects of the cutting amount at the waistline on the jacket appearance evaluation and movement functionality, and to suggest a proper waistline cutting amount when designing the men's casual jacket for those in their 30's. The researchers prepared 4 kinds of experimental jackets varying the waistline cutting amount: 0.0cm, 0.5cm, 1.0cm, and 1.5cm. The results of the study are as follows: Regarding the front view appearance, the jacket with the 0.5cm cutting amount achieved the highest score (6 out of 9). On the side view and the back view, there was no meaningful difference. However, the jacket with 0.5cm cutting amount achieved the highest score (4 out of 5). On the other hand, on the movement functionality, there was small statistical difference; the 1.5cm experimental jacket received the highest score in the most areas. This is resulted because if the cutting amount was increased, equally with the V-zone area which gives room for movements. This result showed the difference from the previous research of men in their 20’s,where 0.0cm achieved the highest test score for both appearance and movement functionality. Therefore, this study suggests using the 0.5cm and 1.5cm for the waistline cutting amount; for the jacket appearance 0.5cm is the best while the 1.5cm is better for the movement.
