CLO 3D Simulation

Digital garment prototyping using CLO 3D software. We build your garment virtually so you can review fit, drape, and construction before committing to a physical sample. Reduces revision rounds and gives your manufacturer a clear visual reference alongside the tech pack.

Deliverables
3D garment simulation video
Virtual fit and drape preview
Fabric behavior modeling
Panel placement review
Pre-sample fit corrections
Delivered alongside tech pack
Turnaround 3 — 5 business days
Delivery MP4 video file
