The normal image for Pewdiepie on the intranets~ is a white shirt with a brofist and then PEWDIEPIE in black lettering below it. Then light blue jeans, and black converse shoes with white laces.
Pewdie also has light brown hair.
Another form is where Pewdie is has blonde/brown hair that is very shiny and then an all black suit and shoes that is very shiny to! XD
I think more people will understand your cosplay if you do the first one just cause its more recognizable...and then having stephano would be awesome XD
