what do you think of my Halloween costume?

I am going to be Derpy Hooves! I'm going to dress up in grey shorts and my new gray Derpy T-shirt. Actually, I'm trying to be her at nightmare night! Like I said I would dress up in gray but I would get a bunch of Paper bags on me. For my hands, I would only make my fingers stick out, maybe, wear a paper bag hat, and make a hole through the bottom of the bag for my shoes! what do YOU think about it?
