Arda also has the Inigo wig
, which comes in the shade Spanish Brown 050. You could trim and style that wig to look like hers. As for the hair tail, maybe buy the Long Bang
in the same shade.
This Yuna cosplayer used the Eowyn wig
(from Arda), and chopped off the excess length.
Either option, you would have wig fiber for the tail-thingy. Good luck!
