As far as punk rock inspired shirts go this one is
Color: Off White&black, Size: XX-Large
The shirt looks nice but the material isn't what it looks like in the picture. It's actually kind of thick, almost like a weaved cotton pattern, if that makes sense. I got it during a heatwave, couldn't wear it. But if you're looking for a decent fall weather t-shirt, well worth the grab.

Go up a size
Color: Off White&burgundy, Size: X-Large
