Bought 'Large' size. Shirt goes down to my in-seem (like an XL or XXL), yet it fits as snug as a 'Medium' in the torso. I have several other T-Shirts that are DC / Marvel Licensed; they are 'Large' and fit very comfortably.

The overall quality is great; the logo is awesome. The faded look is more appealing to me, and there isn't a thick irritating 'sticker' on my chest.
