FullMetal Alchemist Milla Armstrong cosplay help?

Where can I buy boots that match the ones on the anime(just not online) and what site would have the winter jacket she wears? I cant find anywhere that sells the jacket Ive looked online everywhere I google and everything please give me a site I can trust to actually send me what I order NO EBAY! I don't trust them. and any suggestions on hair dye for her hair I have her kind of haircut but my hair isn't that bright and I have thick hair so do you suggest 2 boxes of dye?
