Maybe its just my budget monitor, but isn't that a solid brown coat (albeit with a h-bone pattern)? If so, why would a checked shirt be 'busy'?
It's not solid. True, the pattern is not loud, but it's just loud enough to make checks a bit hard. I'm not saying it would necessarily look bad, just that I'm not sure I would like it.
In any case, I don't have any decent winter check shirts.
