Abstract
The purpose of our study is to make a slacks pattern that may produce slacks both beautiful and functional.
Our approach, therefore, is made from the standpoint of clothes construction ; circular surfaces of the lumbar region and thighs were opened out and made flat so that we can trace and measure the movements of those parts of the human body. Through the experiment we can determine where and how much “expansion” and “contraction” take place.
Our conclusions are summarized as follows.
1. With regard to the longitudinal direction, the most expanded part is the upper part of the central line of back thigh, the rate of the expansion amounting to 128%. The average expansion is 4.5 cm.
2. The portion horizontally expanded most is between the side line and the central line of back thigh at the waist. The expansion is 12.3%. On the contrary, around the hips contraction takes place.
