The famous kazekage hat was used many a time, by the third kazekage (father to gaara), the fourth kazekage (who didn't last long against orochimaru) And most famously, Orochimaru.

As always, heres a picture of what a completed orochimaru pretending to be kazekage, can actually look like ^^ *Note* This is only for the hat, the robe is also available from me, but the other parts belong to other developers.
