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.
