/cgl/ - Cosplay & EGL

K guys. I've got a problem, well, not really my problem, and it's not really a problem yet...But my friend wants to do a SnK cosplay. The con is in a month and he hasn't even started making his cosplay. Like seriously nothing. I keep nagging him seriously every time I see him, telling him it's going to take a lot of work and he just goes ya ya I've got lots of time. I hate to sound like an asshole, but I know it's going to look bad, should I tell him? Let him go ahead and try? I've offered to help out, but he seriously thinks he still has all the time in the world, I don't even know why this is frustrating me so much.
