Blue Overalls

I'm going to a convention, and I have a cosplay, but I was just curious if there were any other characters out there that wear blue denim overalls Ryuichi addition of gravitation, and Of course Mario and Luigi (which is what I am coming up with) Thanks! :)

You could at wallpapers of different series.

Hmm ... It is a difficult question ...

I do not think anyone can answer your question better than you said yourself, lol. x]
