Most women know that regardless of the clothes on a woman, any true assessment can be made from the way she accessorizes an outfit. Could the allure of Wonder Woman be merely the fact that she accessorizes in a unique and utilitarian fashion?
Is it the tiara? More than a mere sign of her Amazonian royalty, the tiara also serves as a boomerang with razor sharp edges. Granted, with the edges being so well honed, there is the curiosity as to why it doesn't wreck her hair, but perhaps that is an indication of the her toughness, down to the follicular level.
Or is it the bracelets. They deflect bullets. Granted on a normal mortal this would be of little use, but because of her speed she can adequately protect herself with her bangles.
Even the earrings have been used as throwing stars, though rarely.
Clearly getting the maximum usage from every aspect of her wardrobe, she's a wonder of pragmatism.
