this became big because celebrities like Kanye wore it. but honestly, it's more about who wears it. this fat rich kid at my school wore it once and it honestly looked like it came from H&M, not a $300 sweatshirt
@curtisbhttp://knowyourmeme.com/memes/three-wolf-moon One became an ironic satire shirt and the other is a piece of designer clothing that costs ridiculous amounts of money. No real difference in the actual product other than the graphics but I wouldn't say the Rottweiler is the same as the three wolf moon shirt.
