The Design and Analysis of the Bra Fit on V-Stitcher 3D Software s

This paper presents the results of research and design of women's bras and analysis of the product's fit on 3D simulation software, V-Stitcher. The study was conducted on 130 females aged 25-35 years old. The research results were divided into four body shape groups from the sample based on classification criteria for FFIT body shape, as measured by principal component analysis, factor cluster analysis, and ANOVA test on SPSS software. Group 1 has 51 people, group 2 has 24 people, group 3 has 51 people, and theb last has 4 people. In each of four groups, choose the one with the highest percentage by sample number to design the base pattern. The products are evaluated on the model to check if the bra is comfortable when people wear it. Besides that, products are simulated through 3D V-Stitcher software to check the fit through the display of different colors on the tension and pressure charts. These evaluation results are checked for reliability by Cronbach's Alpha coefficient. The results of this study provide a way to assess the fit of clothes in accordance with the current 4.0 trend.
