What is the best style of collar to wear open? I looking at picking up a shirt or two from Jantzen, but I wondering about the collar. I would most often be wearing it open rather than with a tie. Clearly, the best would be a sport collar which has a nice roll and no top buttons, but alas it is not an option. I like the look of a shark fin collar when closed, but I imagine it looks rather unusual when open. I've tried to look for pictures, but after several tries at searching with Google and only finding shark costumes I have given up.
