"Need" is just a fiction. As is "should", "must", "value" and "importance".

It, indeed, makes the most sense that she would wear something worn by ancient Greek warriors.
"I'm not arguing that with you. I know he can get the job, but can he do the job?"

Also, it is a reference to very early Wonder Woman comics from World War II era since she wore a skirt back then also, I think
Technically she wore culottes which soon became biker shorts which soon became Speedos.
That said, I never had a problem with a WW wearing a war-skirt/pteruges (like in

And, if I am correct, she's wearing a similar skirt in the Rebirth Comics also. Though, I may have gotten her confused with Supergirl. At any rate, I think the skirt that Wonder Woman wears is a good costume decision.

Actually, I wouldn't mind if it stayed closer to the comic book version. And it is not really a G-string.

Booty shorts

Don't worry, I'm sure the Asylum knockoff will feature Kitana Baker in some sort of G-string gear.
What's missing in movies is same as in society: a good sense of work ethic and living up to ideals.
