Creating the Perfect Avatar Costume is certainly going to be a high priority for many this Halloween season. Standing out from all the other Na’Vi running around in October will take attention to detail.
You could just run around naked, covered in blue paint and call yourself an Avatar NaVi. But that would be stupid, and you would look like a jack ass.
The important details for a solid Navi Costume will include a great Avatar Makeup Job and even possibly Avatar Masks or Prosthetics. But, the body paint, costume, ears and tail will really fill out your Na’Vi outfit.
Low quality, throwaway masks and costumes can be found at any costume shop, I imagine, you know the type of crap , you find in a Captain crunch box.
But, High quality special effects quality Avatar props do exist and with a little digging can be found at very affordable prices.
The best options I have discovered so far:
