On the side seam, I marked from the XS at the arm to L at the waist. I lose a lot of the upper side seam curve that wraps the arm when I do that adjustment.
To be at the elbow, I would need to shorten the arm length another 1-1/2 inches. This would make a straight side seam to the Large waist width. No curves at all.
Is it better to leave the arm length longer and keep at least some of the curved shape?
