Classification of Curved Shapes for Tight-Fitting Bodice Patterns of Young Men Using Concentrated Gaussian Curvature

Having developed a new concept for studying men's clothing design using “Concentrated Gaussian Curvature by angle (Kc=2π-θ)” derived from the conservation law based on the Gauss-Bonnet theorem, we classified similar curved surface shapes of male tight-fitting bodice patterns (T-pattern), regardless of size. Each total value of Kc of the five darts and the three boundary lines of 151 young men's T-patterns is a consistent 720 degrees. Analyzing all eight Kc items on the T-patterns, the curved surface shapes were classified into three T-pattern types based on the shoulder slope combining approximately similar number with two separate groups. The sloping and square shoulder T-pattern types were categorized by small or large chest and back shoulder curved surfaces while the standard shoulder slope T-pattern type had convex back surfaces.
