Not sure what the thinking is but the cover and solicit for May’s Worlds’ Finest shows and says the “classic” Power Girl costume is back.
As Power Girl returns to her classic look, DeSaad wreaks havoc on her tech empire—and PG and Huntress find themselves hunted by the talented torturer from Apokolips.
Given how truly unattractive the other costume was and its propensity for being torn off to show even more than the classic “boob window” did, I can’t say I’m unpleased.
I just hope there isn’t some kind of cosmic adjustment required that will bring back the “belly window” costume for Helena.

I love the boob window costume (when drawn by reasonable humans) and I don’t care who knows it. Welcome back, boob...
I’m more than happy to see the “boob” window costume come back! Let’s just hope it holds up better than the redesign.
only person who stopped caring about what she looked like, and kept loving her
Bertinelli back.
belly window is gone...good. What’s the point of all that armor if she leaves her vital...
YAY
Surprisingly this makes me happy.
GUYS THE BOOB WINDOWS IS BACK @TarunaD
lord. We do not need completely over the top costumes that scream her link to Superman by slapping a giant ‘P’ somewhere...
finally looks like Power Girl again!
