This one was praticaly ready made. I had all of the materials needed lying around the house. The Wig was the only challenge to get but I got lucky and one was found at a thrift store. It didn't cost me but a couple of bucks.

I went with the School Uniform version because one, I was still somewhat green to costume making and two, who doesn't love the school boy attire? I was sad to not have found a Shinji though.
