I am far from the most knowledgable, but I can say that the sizing can be a pain. You need to know how to work with photo shop files I think. I bought a file for Punisher from orhader and he resized it for me. Only problem is that it didn't fit. Maybe it was because of the seamstress I used. That is the next issue, finding someone that can sew it for you. I took it to numerous seamstresses where I live and they all looked at the print like it was written in some alian form of arithmatic. I would suggest going with someone who knows how to do these. Trophywife is in the JY and does them, I don't know how much she charges but she has done quite a few. I found a person at a fabric store who did it cheap, but it was done cheaply and it was done wrong. Don't know why it is so hard to find someone to sew these, they are basically a pattern, you just sew, right?
I really haven't been much help, but I hope it does help in some way.
