  The standardized sizes used in the garment industry do not cover the range of
individual differences in body shape for most people, leading to ill-fitting
clothes, high return rates and overproduction. Recent research efforts in both
industry and academia therefore focus on virtual try-on and on-demand
fabrication of individually fitting garments. We propose an interactive design
tool for creating custom-fit garments based on 3D body scans of the intended
wearer. Our method explicitly incorporates transitions between various body
poses to ensure a better fit and freedom of movement. The core of our method
focuses on tools to create a 3D garment shape directly on an avatar without an
underlying sewing pattern, and on the adjustment of that garment's rest shape
while interpolating and moving through the different input poses. We alternate
between cloth simulation and rest shape adjustment based on stretch to achieve
the final shape of the garment. At any step in the real-time process, we allow
for interactive changes to the garment. Once the garment shape is finalized for
production, established techniques can be used to parameterize it into a 2D
sewing pattern or transform it into a knitting pattern.
