I like the shirt.  The bat signal on the shirt is more subtle than most, mine perhaps slightly more so than in the photo.  I got an XL and it is certainly a full XL. I would say these shirts run true to size or on the large side. Some shirts I have purchased recently ran small or were designed to be more tight fitting than average, not this one for sure.  The shirt is also not tapered, it is very "boxy" in shape just like it appears in the photo.  It must have been packaged shortly after manufacture as there is a pretty strong odor when first removing it from the plastic bag.  So I would recommend washing before wearing.  Otherwise I like the shirt and hope the emblem fares well in the wash over time.  To try to help with that I wash in cold and turn shirts inside out when that is in question.  No surprises so am happy with this shirt.
