Abstract
Recently, young men have become more muscular, as they have become increasingly more interested in health and their physical appearances. The trend these days is to wear slim suits to accentuate their figures. Men's pants are the one of the most general clothes which men wears. While pants are an ordinary item of clothing, most muscular men have fitting problems with ready-made pants. In view of this, this study aimed at developing a prototype pants pattern for muscular men. In this study, five muscular men were selected for wearing tests. The regression formulas, in which muscular men's body measurements were adopted, were applied to unsuitable body parts, especially the body parts determined inappropriate based on the results of the existing pants pattern wearing tests. After going through the first and second pants pattern wearing tests, the final pants patterns were developed that were suitable for muscular men. The results of the study were as follows: In order to solve the problem of the insufficient of ease due to the development of the hip muscles, the crotch length was made longer, (0.08${\times}$hip circumference+17.648)+1.5cm and front crotch width and back crotch width were made wider, 1.0cm each than those of the existing pants prototype patterns. The ease of 0.5cm was added to the hip circumference/4+2.5cm because of the development of the hip and thigh muscles.
