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.
