First,others send them to you. About this something farfetched way,you must know many coser friends first and your relationship must be much firm that if they grudge to get part with their cosplay costumes,may be you can rob them.LOL.
Second,buy on the exclusive shopes.There are many official cosplay costumes in Japan.But if you are in China,may be first you have to fly to Japan.
