Ease distribution in relation to the X-line style jacket. Part 2: Application to pattern alteration

A model of ease distribution in relation to the X-line style jacket has been developed in Part 1 of this two-part series of articles. The prediction of segmental girth ease allowance (SGEA) was carried out using the ease distribution model (EDM). The EDM was verified by comparing the deviations of the predicted SGEA with four extra jackets in different dimensions. Based on the distribution of SGEA, pattern alteration could be implemented by effectively adding the SGEA into basic block at the corresponding position instead of adding girth ease allowance at the edge of the pattern. The pattern alteration using the EDM was evaluated by comparing 18 parameters of newly produced patterns with those of draped patterns. The fitting of the patterns was visually assessed by three experts in garment design. Finally, the advantages and disadvantages of the proposed model are discussed.
