This is my third cosplay, and my first time actually creating a costume from almost scratch.
I bought a black jacket at Goodwill, then sewed in all those stitches myself. I already had some black pants and sewed the stitches in there as well. I used some iron-on transfer thing to get the school logo on there. I also sewed the collar on. Sewing is so manly. The wig was bought off eBay.
I also made some props for the Persona costume. I had a plush fox which I turned into the "Mysterious Fox", sewing the bib myself. I also attached some velcro to the fox and my jacket so that he could sit on my shoulder while I walked around.
I printed out a Fool card, then created a base for the card to make it stand up, as if it were "floating" in my hand.
