Hello, I have a few questions about taking measurements from existing shirts.
In the first image which is the correct way of measuring the half-armhole, the red or green arrow? I am aware that it has to be a curved measurement, it is just the placement that I need help on.
The second question may seem slightly pedantic but please bear with me. In the attached image which is the correct way of measuring from left to right seams? The red arrow includes both seams and adds 2cm to the measurement while the green arrow stops at the beginning of each seam.
Thanks in advance for any replies.
