I don't want to cramp your style, but I don't have high hopes for you my friend. T shirts run TTS, and are a little wide on the body except they are cut short. I anticipate that it will be a "boxy" look, and very much so if you went a size up. For their shirts, if anything, I might recommend sizing down if the head opening weren't so small.
Thanks for the info. I purchased it half off on Mr Porter, so, I figured it's worth trying. I was actually worried about the length more than anything, so, the fact that they're cut short leaves me a little hope.
