This is my first shirt from Chan, and I'm getting ready to order a few more (can't wait around forever for Jantzen). Should I change anything on my measurements? What do you think about the following changes? 1) shorten the shoulder measurement by .5" so that the shoulder seam is higher up on my shoulders. 2) lengthen the sleeves by .5". My left arm is longer than my right, and it feels like the sleeve is a little short. 3) make the armholes about .5" bigger to just slightly loosen the arms and make the shirt a little less restricting. Anything else? Thanks!
