i personally would give my vote to Ino. Ino needs more love for cosplay XDD namely, go ahead and do timejump ino.
but as DarkenedWings said, if you plan on killing your hair and dying it. You can go ahead and do Hinata and Sasuke. I did
I used garnier black/blue dye and it turned my hair black and used those comb on tempo hair things to help bring out the blue tints
. So I ended up being Hinata AND Sasuke XDDD
