The purpose of this study was to present a making method of jeans pattern with high fitness after deriving the appropriate shrinkage rate by material and washing process. Research Method of jeans pattern was presented after applying the optimized shrinkage rate. According to the result of the exterior evaluation of test jeans, all 6 jeans were rated high with scores close to 3.5. Following the evaluation of satisfaction of usage by physical movement, the highest ranking was in the order of walking with normal steps, back bending $90^{circ}$, chair sitting, climbing stairs, and squatting. The shrinkage rate by physical area showed the highest score in the order of pants length, waist circumference, thigh circumference, knee circumference, hem circumference, hips circumference. In addition, the shrinkage rate was higher in warp direction than weft direction after washing finishing. As for the result of addition and reduction of pattern measurements by parts of jeans, waist circumference was $2.5{sim}5.2cm$, hips circumference was $-1.8{sim}2.8cm$, thigh circumference was $-1.3{sim}2.0cm$ and knee circumference was $-1.0{sim}1.7cm$. Also, hem circumference was $-1.0{sim}1.8cm$ and pants length was $2.9{sim}6.2cm$. That is, this results showed a wide range of addition and reduction according to material and washing finishing.
