The surfaces of 3D models which were constructed in our previous study were developed for each of 48 elderly women. The dimensions on the developments were analyzed. In comparison with those of young women, the elderly women's torso surface dimensions were significantly different in several aspects. The back neckline was narrower and shallower, the front neckline was deeper, the shoulders were narrower, and the bust point was lower. Above the armpit level, the difference in length between front and back was larger and the angles for dart placement were larger, allowing for the more rounded back of elderly women. The principal components characterizing the individual shape of various two dimensional torso surface areas were extracted. The meanings of those components were similar to those of young women except for the second component which was interpreted as the degree of inclination of the upper back. These results suggest the need for special consideration regarding alterations of dress patterns when ready-to-wear and custom made dresses are designed for elderly women.
