Digital 3D garment development process: From concept to virtual prototype

Abstract

The digital transformation of the apparel industry is increasingly driven by the integration of 2D pattern development and 3D virtual simulation technologies. This study focuses on the digital 3D garment development process using VStitcher (Browzwear), presenting a structured workflow from the initial design concept to the final virtual prototype. The proposed approach emphasizes the transition from traditional physical sampling to digital prototyping, enabling improved efficiency, faster design interactions, and reduced material consumption. The workflow includes 2D pattern construction, material definition and mapping, virtual garment assembly, 3D simulation, and fit evaluation on a digital avatar. The results demonstrate that integrating 2D and 3D environments creates a continuous feedback loop that supports iterative refinement of design parameters and early detection of construction and fit issues. The study further confirms that virtual prototyping, supported by styling tools, enhances garment evaluation by enabling advanced manipulation and simulation of manual fitting adjustments. This contributes to reduced physical sampling, improved development accuracy, and increased workflow efficiency. However, simulation accuracy remains dependent on precise pattern construction, material parameter definition, garment complexity, and user expertise, while certain tactile fabric properties cannot yet be fully replicated digitally. Overall, the study demonstrates that 3D garment development systems such as VStitcher provide a robust methodological framework for more efficient, accurate, and sustainable apparel product development in both industrial and educational contexts.
