Why don't you try buying a pattern from a store like Jo-ann's that sells fabric? Making a pattern by taking apart a finished trouser will not be the same. The fabric has been distorted by sewing and pressing. There are multiple steps to making a trouser for yourself. Learning to sew,and learning to adjust a pattern to fit. Have you looked into classes at schools or stores that offer training classes?
