  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 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 steps
and rest shape adjustment steps 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.
