Optimization of Bodysuit Panel Design Based on 3D Virtual Clothing Pressure Boundary Analysis According to Body Shape

This study aimed to develop form-fitting bodysuit patterns tailored to four representative body types of Korean women in their twenties and to determine optimized pressure panel configurations for each. To accomplish this, we analyzed clothing pressure distribution using CLO 3D virtual fitting simulations. The bodysuit patterns were applied to avatars representing each body type, and pressure boundary lines were extracted with a proprietary tool called BePred. We established pressure thresholds of 1.2 kPa for the upper body and 2.4 kPa for the lower body. The analysis revealed consistently high-pressure areas around the lateral thighs and buttocks across all body types, though the specific shape and extent of these areas varied. Based on these findings, we developed customized pressure panel designs for each body type and refined them to enhance both sewing efficiency and aesthetic appeal. Expert evaluations confirmed the final designs' visual attractiveness, adaptability to diverse body shapes, and potential for fit adjustments. This study presents a viable and systematic design methodology for creating customized, form-fitting garments informed by pressure distribution data, showcasing promising applications in the development of high-performance compression apparel.
