To improve the adaptability of customized blouses and achieve rapid pattern generation,a customized blouse pattern generation scheme based on human body size differences was explored.Firstly,one standard body sample and 23 samples covering various body characteristics were selected from 118 initial screening subjects through anthropometric experiments.Then the standard pattern was drawn and the sample fitting evaluation was car-ried out.Based on the size differences between 23 subjects covering various body types and the standard body,the corresponding pattern adjustment rules based on human body size differences were developed,and the fitting evalu-ations of the adjusted patterns were conducted to verify the feasibility and universality of the adjustment rules.Fi-nally,a mathematical model was established based on the pattern adjustment rules,and the automatic gen-eration of custom blouse patterns was realized using Matlab software.The results indicated that the selected measurement locations and established pattern adjustment rules were suitable for personalized customization of the blouse,and the established program for automatic generation of customized blouse patterns was feasible.
