Renee O'Connor's Amazon Queen costume.  Closeup shots are below.  I do not have the Queen Mask (it's owned by an American fan in New Zealand) and I never found the purple cloth underskirt (it wasn't part of the package).  I obtained this online during It's A Wrap's auction of H:TLJ and X:WP props and costumes.

Close-up of Belt detail. Note the use of real feathers throughout the costume.  Necklace is braided leather and both metal and real feathers.

Close-up of Dagger sheath (dagger is missing).  Close-up of two of the armbands and belt and bra detai.  The small plastic envelope holds a metal feather earring.
