Hello, everyone. I'm a big guy with a relatively skinny and long neck. I was measured as having a 19 inch neck. The thing is that when I get shirts in a 19 neck, most of them are loose and i have too much space between my neck and the collar. But, a couple shirts I already own are the right size for me and are labelled as 19. I am thinking about ordering a Jantzen shirt just to try them out, but what if the collar is too large at the 19 that I'm going to give them? Should I maybe go 18.5 instead? Thanks for any (good) advice.
