Abstract: As the basic pattern of female garment, Donghua’s basic block has been developed for ten years based on the body measurements from young women. In order to improve the construction of Donghua’s basic block to be applied in a large range of different ages, 23 body measurements of 182 subjects aged between 18 and 40 in East China were obtained from 3D body scanning. Subjects were classified into four age groups: 18-24, 25-30, 31-35, and 36-40. One-Way ANOVA was run to investigate the potential presence of significant differences on the means of measurements between characteristics of each age group. Then, the regression equations were revised by adjusting regression constants for different age groups. The evaluation results showed that the sample produced by revised basic block had a good fit.
