This shirt gets away from the RL wardrobe staple. It's a piece that is pulled out on occasion, just to add a little flair. If worn in this way, I think that this shirt could be worn in good taste, but if worn more than a couple times, I feel that this shirt may become "that shirt". You know, "that shirt" receives more eye rolls than a emoticon in an business email. Don't be pretentious, be subtly pretentious.
My call: Bad taste
