Was getting a bit tired of cosplaying as Mars/Scarface, since no one knew who he was, so I decided to go for a better known character: Kevin Mask. Unfortunately, I got the same results with this. .. People mistaken me as Optimus Prime and Alphonse. ;_;
The mask was made from cardboard, fun foam, and plaster cloth.
Trenchcoat bought from qqcosplay.com
