Power Girl's boob window needs no explanation; it's purely aesthetic and that's fine because her costume has no practical component to it. Her book is also fun and flirty, so it fits.
Huntress on the other hand is a non-powered, Catholic, mob-connected vigilante in a dark and brooding line of books, so the choice to give her a non-protective, sexy costume clashes both with the level or suspension of disbelief being asked, and the general tone of the stories she's appearing in.
