Abstract
The objective of this study was to develop guidelines for clothing sizes, and to develop designs for ready-made clothes which are comfortable for the wearer. The movements of the cloth of wearers' shirts as well as the measurements of the wearers' bodies were measured simultaneously and then analyzed with a three-dimensional motion analysis system to determine the ease of movement was examined with respect to clothes of various sizes. A wearing test using a front-opening shirt was conducted on 22 young women. Subjects wore five sizes from one small size to three big size than their standard clothing size. The effects of the sizes were investigated in terms of their "ease of movement" and "sensory evaluation of wearing." The results showed that the subjects who wore shirts from one big size to three big size felt larger range of motion of the shoulder joint than the wearers of the one small size and the standard clothing size. It may be said, then, that it is not necessary for people to wear larger shirt than one big size. Wearers prefer clothing which exposes part of their body when they move and clothing which they have to adjust after moving. The research found that this type and size of clothing is optimal for wearers.
