Fit looks pretty solid on this but one thing is catching my eye in particular, the wrinkling right below the shoulder seam. Does anyone have ideas about what's causing the rippling? It looks to be emanating from the armhole. The exact same things happens on all my shirts, and I've been trying to figure out how to fix it over a number of orders but so far have been unable. I've tried increasing the armhole and sleeve width (at Luxire's urging) but it hasn't fixed the problem yet.
