I know that most casual Fett fans don't go to quite the extremes of accuracy that some on these forums do, to them Fett is Fett and if he looks vaguely like him, they are fine with it.
Casual fans/observers really don't care about such things. Having said that though, that is well overpriced, especially for a casual costume!
