Ah~ Here is the historical account of this shirt.
I bought this shirt when I was working at a business casual work place so the shirt could be worn with a pair of black slacks with no prob.
Now, I work at a suit and tie only work place and thought I mix this shirt into my rotation. Also, I cannot burn a shirt that I dropped three benjies on (IDIOT). It's Zegna and I liked it so I just laid down.
Keep it for casual if you can't bring yourself to burn it. Or there is always charity. In extremis, keep it for casual! But either way, the lesson learned is "don't ever buy the label".
