I know I'll get hanged for this comment, but you can literally buy a Char outfit from ezcosplay for like $99. With it that cheap, you can buy it and alter it a bit to make it look nicer, but you'll have all the bits sans helmet.
As for the Helmet, I've seen STL files for it available online. Do you have access to a 3D printer? If not you'll have to go the ol pepikura/bondo route
