Although they generally undergo less change in somatotype than other age groups, women in their early twenties have postural changes incurred with their inappropriate postures during the growth period. Since such somatotype changes reduce their satisfaction in the fitting of ready-made clothing, the study intends to examine the inadequate postures and life habits of women in their twenties and to analyze their self-recognition and actual conditions of the bad fit of ready-made clothes. A survey questionnaire was conducted on 225 customers and 29 sellers of ready-made clothes. According to the result, it was found that their inappropriate postures had made their back and shoulders undesirably bent and led to their low satisfaction in the fitting of ready-made clothes. Therefore, it is necessary to perform researches for developing renovated design in consideration of their somatotype changes.

The purpose of this study is to most appropriately develop maternity wear according to the preferences of specific age groups of pregnant women. The specific age groups were women in their twenties, early thirties, and late thirties. This survey was conducted in the metropolitan area around Seoul, South Korea through a questionnaire given to 150 pregnant women. The study found that pregnant women purchased significantly cheaper clothes after their pregnancy than before. The participants responded that they mostly bought clothes using the Internet, but they also reported many instances of returning the clothes due to fit and sizing. It was shown that women in their twenties tended to consider the price, design, and activity more than women in their thirties when purchasing maternity wear. The study showed that pregnant women tended to wear maternity wear from early in the pregnancy-preferring leggings, one-piece dresses, pants, shirts, briefs, and bras with the girdle on the outside. More women in their late thirties purchased maternity support belts than younger age groups. In any case, in purchasing maternity wear, clothing features that the respondents focused on were comfort, functionality, fit, the covering of their body changes, and fashion. Still, many respondents 35 years and older reported more interest in safety rather than fashion in comparison to the responses of respondents under the age of 35.

The purpose of this study is to suggest a methodology to grasp the design method of industrial slacks pattern for women in their early twenties. The result of this study is as follows: 1. The result of the questionnaire showed that the design of rear center gradient was most important and the rear center gradient was designed by shifting waist line and hip line to a suitable degree.; below the waist by 4cm, the girth was measured and the ease of $0{\sim}1cm$ was applied to it, and the ease of hip girth was $3.2{\pm}1.2cm$, and rear center gradient was $2.2{\pm}1cm$, and front crotch extension was $2.8{\pm}0.5cm$, while rear crotch extension was $6.3{\pm}0.5cm$. 2. By comparing rear center gradient which was selected as an important design item with total crotch length and hip girth, I selected industrial pattern and educational pattern, and evaluated them on human bodies. In the result of ANOVA analysis, there were meaningful differences in 8 items: the ease of front waist girth, the ease of front abdomen, the ease of front hip girth, rumples in the side lines, the location of rear waist line, etc. 3. The design method of slacks pattern suitable for women in their early twenties was suggested as follows: the location of waist girth is below waist by $2.5{\sim}3cm$; the ease of waist girth is $0{\sim}1cm$; the ease of hip girth is $2{\sim}3cm$; total crotch length is body size - 5cm; rear center gradient is $2.5{\pm}0.5cm$; rear crotch extension is $7{\pm}0.5cm$; front crotch extension is 3cm.

The purpose of this study examines the fashion-related concerns of women in their early twenties and their personal thoughts on sociocultural factors through fashion. Data were collected twenty-seven female participants in their twenties in order to examine their traumas related to fashion and how these experiences affect their attitude toward clothing and fashion. Based on this, this study sheds light on what effects traumatic experiences have had on participants' self-esteem. It also provides an in-depth analysis of the problems underlying and reasons for the study participants' fashion choices, and attempts to demonstrate their self-reflection through fashion. Finding of the study was that the participants had a passive attitude toward fashion and built a wall against it. The study results suggest that the very first step to going beyond oneself and developing an active attitude is to try to be proactive and face a challenge related to fashion or clothes that one chooses oneself. Therefore, it is now time for Korean society to shape a culture that respects the unique qualities of every individual and allows free expression of diversity.

The research is focused on relationship between body fat percentage and physical characteristics of women in age group between 20s and 30s who experience great deal of physical change such as marriage, pregnancy, delivery, breast-feeding, and etc. The research used physical measurement of two hundreds women: 50 women in their early twenties, 50 women in their late twenties, 50 women in their early thirties, and 50 women in their late thirties. The research provides base data for women clothing industry by observing relationship between physical figure and body fat percentage rate based on obesity study on body fat percentage, physical BMI, R$\ddot{o}$hrer Index, and Vervaeck Index. Followings are conclusion of the research. The older the ages, the shorter the height and the heavier the weight. Recognizable differences in circumference, thickness, and width rather than in length are found. Also recognizable increases in average body fat percentage and average physical characteristics by age have found. By observing body fat percentage and physical measurements, it was revealed that weight has more effect on body fat percentage than height in all ages. Circumference, width, and thickness have more impact than length measurements among physical measurements. Main body or upper body has more impact than legs and arms or lower body. Body fat percentage increase rapidly by ages. 2.0% of age 20~24, 20.0% of age 25~29, 28.0% of age 30~34, and 54.0% of age 35~39 were sorted as obesity.

This paper proposed the sizing system for women's upper clothes in order to improve clothing fitness and raise the productivity. The sizing system was classified according to 5 body types and 5 age groups. The size intervals of the basic dimensions were established at regular intervals centering around their means. The size interval of stature was 8cm centering around 158cm and that of bust girth 4cm centering around 84cm and that of hip girth 4cm centering around 92cm. Frequency distribution on the size of upper clothes showed that the most frequent size were 96-96-150 in the longest-fattest type, 88-96-158 in the long-fatter type, 84-92-158 in the medium length-fat type, 84-92-166 in the Short-balanced type, and 76-88-158 and 80-88-158 in the medium length-balanced type. The number of the sizes of upper clothes, which had frequencies more than 5%, was 32 and each size was presented with waist girth, back waist length and sleeve length. The size system classified by age group had 22 cases in the early twenties, 15 cases in the late twenties, 21 cases in the early thirties, 19 cases in the late thirties, and 15 cases in the forties.

This study was conducted to analyze the characteristics of women's body somatotypes by direct measurements. Through the classification of degree of obesity and silhouette, women in their 20s who have a great interest in body somatotype can grasp their real somatotype and recognize their obesity rate and silhouette easily. The results are as follows: 1. Average sizes of subjects for this study were: height 160.3cm, weight 52.2kg, bust 83.7cm, waist 65.7cm, hips 91.1cm. And average values of each body mass index were: BMI 20.3, Rohrer Index 1.27, Vervaeck Index 84.8. 2. For the BMI value, the Average Numeric Index of normal somatotype was the highest, 76.9%. The Rohrer Index of underweight somatotype was 34.3% and the Average Numeric Index was 1.12. In the Vervaeck Index, underweight somatotype was 35.7%, and the average Numeric Index was 79.1, while the overweight somatotype was 7.4% of the Vervaeck Index and 100.8 of the Average Numeric Index. So the index which had the largest range of normal values from the same subjects, was the BMI, then the Rohrer Index, and finally, the Vervaeck Index in that order. 3. In the result of sorting bodies with silhouettes, when drop value were used to sort, N type (normal somatotype) was 69.4%, H type (one has similar sizes in waist size and hips) was 20.4% and A type (one has big hips) was 10.2% in that order. Among people in their early 20s, A type was 12.1%. H type was high, 22.8%, among women in their late 20s. When Sinozaki's method of classifying body types was used, ideal somatotype was 86.6%, A type was 7.4%, I type was 5.6% and X type was 0.5%. Women in their late 20s showed higher rates of ideal somatotype, the rates of A type and I type were lower than women in their early 20s.

Objectives: This study aimed to compare the factors of dietary and health behavior according to the employment in women in early adulthood and to analyze their relationship. Methods: In this study, adult women aged 20~29 who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) 2016~2019 were classified into two groups depending on their permanent worker status, namely tenured employees (n = 254) and temporary employees (n = 377). Dietary habits (prevalence of skipping meals, food nutrition label use, etc.), nutrient intake, and metabolic syndrome factors were analyzed. Results: The tenured employees' group showed a significantly lower proportion of subjects who skipped breakfast (P = 0.0254) and significantly higher daily energy intake (P = 0.0264) than the temporary employees' group. However, there were no significant differences in the intake of energy nutrients and most of the micronutrients per 1,000 kcal of energy intake between the two groups. The proportion of subjects who consumed energy nutrients under 75% of the estimated energy requirement (EER) was 38.11% in the tenured employees' group, which was significantly lower than the 48.30% in the temporary employees' group (P = 0.0159). In economically active women aged 19~29 years, the odds ratio of low HDL-cholesterolemia prevalence was 1.80 times higher (95% CI, 1.06-3.06) in the temporary employees' group compared to that in the tenured employees' group after adjustment for confounding factors (P = 0.0295). Conclusions: In conclusion, among Korean adult women in their twenties, temporary employees showed inappropriate eating habits such as skipping breakfast, and had abnormal blood lipid levels.
