project cosplay

hi all. I was new in the world cosplayer cosplay ^ ^. I will start the first project is a yuika cosplay in anime hanasaku Iroha.

the first thing to do is prepare a wig and seifuku. maybe I'll buy a wig online. and to seifuku, I also prefer to buy via the Internet. how do you think?
oh yes, anyone can tell me. how to choose fabrics that are used to make clothes? oh, I was not able to distinguish the types of fabric.
I am the new cosplayers. hopefully, I can be a talented cosplayer. hehehe
