In order to make up the fitting garment,the pattern shape is different from the common structure on garment. Besides that,the way of grading series pattern will be different. The fitting garment with 45° fourpiece extraordinary diagonal structure line was taken for example.The series pattern is made directly and the grading rules are found by analyzing the geometric relationship of each grading point in the corresponding pattern. The research technique for extraordinary structures garment is offered. It gives the pattern-maker in garment industry exact grading data on fitting garment with 45° four-piece diagonal structure line. It has practical and scientific guiding sense.展开更多
