This study was to carry out interview and survey of currently marketed foundation garment, focusing on manufacturers, on the basis of data of Year 2004 SIZE KOREA in 2004, to re-establish suitable age range and standard size, to simplify size interval scale and size system and to revise the standard for consumers' easy understanding and availability; The findings of this study are as follows. 1. Considering the age, in which a bra is worn, has reduced socially, the applicable age range was expanded into $8{\sim}80$ years old, which was divided into for junior and for adult. 2. For bra size, the standard title changed into the foundation garments size standard, in which girdle and bodysuit were included. 3. Basic physical parts for establishing for bra size are underbust and bust. Interval scale of under bust and bust was 5cm and 2.5cm, respectively. And basic physical parts are waist and hip girth for girdle, and underbust, bust, and hip girth for bodysuit. 4. For bra size, underbust girth was applied together with bra-cup size without 'cm' unit. For bra-cup size, difference between underbust and bust was represented as English alphabet. In other words, AAA means that difference between under bust and bust is 5cm. AA, A, B, C and D means that the difference are 7.5cm, 10cm, 12.5cm, 15cm and 17.5cm. 5. For girdle size, waist girth was applied together with hip girth without 'cm' unit. And for bodysuit size, underbust girth was applied together with cup size like bra size, and English alphabet represented hip girth range.

We studied relation between the clothing pressure applied by types of brassiere, postures, feeling of tightness. The main results were summerized as follows; 1. The research subjects of this study were 9 who rate of body fat was borderline and degree of fatness was normal. As a result of clothing pressure, the most prefered value was $36.86g/cm^2$ on sensor 2 in standing position and the next was $34.76g/cm^2$ on sitting position. Furthermore, The maximum value of sensor 2 was $59.08g/cm^2$ (in standing), $57.93g/cm^2$ (in sitting). On the other hand, The average clothing pressure of bra C type was $23.67g/cm^2$ 2. The study of feeling of tightness applied by bra type was high in order of C

This study is on the brassiere of reduce clothing pressure. To set the measurements of bras for women in their 20s, considering the comfortableness in wearing and tightness, this paper conducted a questionnaire survey concerning breasts and bras as well as measurements of body and contact surface pressure. As a result of comparing the discrepancies between the lower chest circumferences of the body and the bra, it was revealed that 67.0% were wearing one that was bigger than the body size. Most of them mentioned 'feeling of tightness' as a reason(60.4%), which suggests there are problems of the total length and elasticity in the process of making bras. The favorite bra types are wire type(57.9%), mold type(24.3%), and strapless type(10.4%).it is recommended that the total length of lower chest circumference be increased. The result and the recommendations of this study are as follows: First, the total length of brassiere be increased by 5cm from the current patterns in the process of manufacturing. Second, elasticity of the lower-side tapes be extended from 120% to 170%.

This study sought to typify and characterize the upper body shape of women with large breasts by classifying only Korean adult women aged 20-69 years whose difference dimension between bust and underbust circumference was 12.5 cm or greater. This study attempted to provide necessary information for the development of upper body clothing for women with large busts. Upper body horizontal, upper body height, shoulder size, upper body length, and shoulder slop factor were extracted to constitute upper body shapes of women with large busts. Upper body shapes of women with large busts were classified into four types: low obese upper body tall body type, high normal upper body short body type, drooping shoulders slender upper body tall body type, and broad shoulders slender upper body short body type. Upper body proportions of women with and without large busts were analyzed as follows. Women with large breasts had narrower shoulder width compared to bust width and waist width. Their underbust and waist circumferences were larger than their bust circumferences. For the development of tops for women with large busts, bodice pattern development was required, taking into account shoulder width, chest, and upper body length. Future studies should focus on angles of busts in more detail. Research should be conducted on the development of bodice by upper body type of women with large busts analyzed.
