• Step 1: Draw in armscye to create an accurate guide.
• Step 2: Use straight tape measure tool to measure from front mid-left armscye to front mid-right armscye.
• Step 3: Compare this measurement with the 3D scan output (if available) and see if it makes sense. If it is vastly different, replace the 3D scan output with your measured value.
