From Human Body Curvature to Flat Pattern: A Tape-Mold Transformation Method for Female Corset Form Design

As a highly fitted garment type that integrates structural support, anatomical fit, and aesthetic form, the female corset has historically relied on empirical judgment, traditional draping techniques, and repeated physical sampling during its construction. These conventional approaches often lead to significant difficulties in the accurate extraction of complex human body curvature information and its subsequent transformation into precise two-dimensional flat patterns. In response to these technical challenges, this study proposes an innovative tape-mold-based transformation method tailored for female corset form design, systematically investigating how intricate human body curvature information can be effectively translated into functional flat patterns. Taking the female upper body as the primary anatomical object, the research establishes a rigorous workflow encompassing key-line marking, protective plastic-film wrapping, precise masking-tape application, strategic division-line drawing, piece labeling, mold separation, flat-pattern drafting, and final toile construction. The experimental results conclusively demonstrate that the proposed tape-mold method effectively preserves the essential curvature information of critical areas, including the bust, side bust, waist, and overall torso. Moreover, it significantly improves the intuitiveness and accuracy of division-line judgment, providing a highly operable path for transforming three-dimensional human body curvature into two-dimensional flat patterns. Ultimately, this method offers a valuable technical reference for advanced female corset research, the preliminary development of highly fitted ergonomic garments, and innovative fashion design education. Future work should further enhance the method's standardization and reproducibility through the seamless integration of advanced three-dimensional digital scanning technologies.
