I boat an organization coat back when I had a lot of money. I bought it from: http://orgxiii.org/commish_organization13.htm
It is custom made but it could fit a lot of people. I only wore it once and for a few hours. I spent $420 on it. O_O I know, it's insane. What can I say I'm a crazy cosplayer. I have pictures of it and I can haggle over a price. I would like it to still be reasonably high though since I did pay a lot for it. I'm just wondering if there's anyone who will pay that much for a coat. Besides crazy me. If there's anyone out there I would love a response! I will send details and pictures if you're interested! Thanks!
