Something like this would allow them to cover her arms and legs, reducing the need for her to have bulging amazonian muscles. (Though not eliminating the need in my opinion.)
I'll say again that I think a great screen adaptation of the costume would be a Xena-like studded leather skirt dyed dark blue and a dark, blood-red leather tunic on top, in addition to the usual gold ornamentation and symbology. No strangely skimpy clothing (taken for granted in comics but doesn't translate well to film) but at the same time it doesn't lose the Amazonian vibe that vanishes when you put a black leather jacket and pants on her.
So what do YOU think the costume should look like?
