The original solicitation proudly proclaimed, "Diana wears her WORST OUTFIT EVER!" but it got cut. :)
.... Who would cut such beauty? ;_;
If we say that Superman was the last survivor of a doomed planet, and Batman was the son of murdered parents, but we have to include all this stuff to explain why Diana is wearing that outfit, we're really starting two steps behind to begin with.
False parallel. Diana is the best of a race of mythical women. This is no more or less complicated than Bruce being an orphaned eight-year-old or Clark being the last son of a dead planet. If someone then asks "well, in that case, why is she wearing the American flag for a bathing suit," that question is equivalent to "if he's an alien, why is he wearing an S," or "so what's with the bat obsession." The answers to which - "it's coincidentally the symbol of his alien parents," and "he realized criminals are a cowardly and superstitious lot, and that something scary and ominous like a bat would scare them," respectively, are again, no more or less complicated than "she wears those colors to honor an American pilot who gave her life for an amazon."
Is there a great deal more to all three of those stories, of course. This is comics. But there's absolutely nothing about the Diana Rockwell story that's particularly more convoluted than any equivalent piece of Clark or Bruce's history, at any level of detail.
You have to forget about those two major parts of her costume to try to make it purely American-flag-ish.
But you've said it's the American flag anyway by saying that Betsy Ross was inspired by the Amazons. Reversing the order of inspiration doesn't change the equivalence.
Also, I must know if you and Sholly Fisch talked about this before he wrote the last issue of SUPER FRIENDS, else I may go mad.
I certainly think it's a little more fitting for Diana to be dressed as the sky
More fitting than saying she dresses to honor a woman from our world, a lowly human, who made an amazing, Wonder Woman-like sacrifice for a perfect stranger? Because I think that's a pretty powerful message to lose for mere astrology.
I mean it's academic at this point obviously, I'm just saying. :)
