Clothing fitness is strongly required in the apparel industry, and draping is an effective tool to increase fitness to the wearers. A more sophisticated and systematic information of the somatotype, accordingly, is necessary for better dress form design. This study was performed to provide fundamental data on middle-aged women`s somatotypes for dress form designers by classifying the torso somatotype and analyzing the characteristics of their somatotype. The subjects were directly measured anthropometrically and indirectly analyzed photographically. Data were analyzed by factor analysis, cluster analysis and analysis of variance. On the basis of the cluster analysis, using 7 factors cores the subjects were classified into four groups and four dress forms for middle-aged women were constructed. By the analysis of moire topography of proposed dress forms that were constructed according to the characteristics and silhouettes of front and lateral views for each somatotype of subjects, three-dimensional characteristics of somatotype and overlapped crosssection diagrams were analyzed.
