A) Anyone have a link to a very good description of where the shoulder seam should lie on a shirt? Preferably, does anyone have a pic? I've googled but there seems to be contradictory pictures and in any case I respect SF's take. B) I've been looking at other men's shoulder seams on the street. Most t-shirts and dress shirt seams seem to fall off the shoulder. Are most of America's men wearing oversized shirts?
