Great Block to start your Proto-1 (Advanced Gusset and sleeve articulation).
Customers need to do:
- Add your circumferences to it. (Change the length or make any adjustment to the design).

I could help with this requirement, and I can make it a full production pattern with the liner, pockets, seam allowance, and all detail. And I can work closely with your Factory side by side in sample processing for an extra charge.
