Why's one side attached to a weird medallion thing and the other side's attached to a rope?>What's wrong with the "stupid hole" in her shirt?
It interrupts the flow of her leotard. At least when you have, say, an insignia or a logo or something there, there is precedent for that among most other superheroes (especially those within the Superman Family). Here, however, it's just /there/, for no other purpose than just the tit window, which cleavage would have been able to give just as much of (if not more than).> Why is that cleavage somehow more reasonable than hers?
You don't see boob windows outside of slut outfits or fancy gowns or some shit. There is, however, abundant precedent for just showing cleavage in general.
And anyway, THAT cleavage is more reasnoable because it combines the more realistic "having open cleavage" look, while the raised collar and carefully placed rope frame the cleavage in such a way as to both emulate the cleavage window in a more aesthetically pleasing manner, as well as to stand out as unique.
