My main issue is we risking taking personality away from some characters who have a naturally sexy persona because in real life there are people who are happy to show that side of themselves. It is true not every female character should be subjected to revealing clothing, but the opposite side to that is there are characters where that's entirely appropriate. I know people want better female characters but that doesn't mean every character has to suddenly button up conservatively. Patty Jenkins kept Wonder Woman's boots because in her own words it was female wish fulfilment, so I think we have to be careful imposing upon women that their heroes should look like. Does this mean guys are still going to fantasise? Well, yeah, but so what? It's not like women aren't given their own eye candy to drool over anytime one of the heroes takes off their shirt. So, I'm all for Black Canary in the fishnets and sexy outfit, it's her iconic look and there should be no shame in showing it. And again, let leave some room for some sexiness, the entertainment world doesn't need to be that bland.
See I hear this argument a lot and I'm sorry but it doesn't work. It's not the same thing. Do these films through in a couple of scenes of Thor with his shirt off, absolutely. Captain America wearing suspiciously tight-fitting shirts, certainly, Bruce Wayne with his shirt off while working out, definitely, etc.
But here's the distinction, those are one or two token scenes of fanservice, which is fine. But that is NOT the same thing as their SUPERHERO COSTUMES looking that way. Captain America wears a costume that at most just exposes his head (if he takes his helmet off). Thor wears a costume that at most exposes his head and arms (and sometimes he wears costumes that armor his arms up to). Batman only has the lower half of his face exposed. Spider-Man has every single inch of skin covered my his costume, etc.
Then you have the female characters, who often have leotard that show lots of skin, or tight-fitting cleavage-bearing corsets, or high heels, or even Black Widow who's outfit isn't inherently sexual often has artists draw her zipper down to bear her cleavage for no real reason, or fishnets, or glorified swimsuits, etc. THAT'S where the double standards come in. Even the way that they're often posed is telling. Male characters are made to look powerful and badass and you want to be them. Female ones, are drawn to give the readers boners and you want to bang them.
Now there are some characters that this works for. For example, I'm fine with Zatanna or Emma Frost looking that way because it's believable. But Dinah, who often needs to run or jump, or fight hand to hand, etc wearing fishnets. No, and I've never liked the fishnets for that reason.
Now you want to do the female equivalent of the male "fanservice scenes." Do something like a female hero is working out in bike shorts and a sports bra, or they're at the beach or lounging by a pool in a swimsuit, or their swimming or whatever. THERE'S more equivalent scenarios. Heck I'm not even opposed to (if it makes sense in-context) love scenes. I mean I'm the guy who made jokes about the movie being R-rated so that we can get a Harley/Ivy love scene for goodness sake, and I had no problem with WW and Steve Trevor hooking up in her film at all. So I'm not prude when it comes to female sexuality, but only in the right context (and the same is true for men for that matter).
And speaking of WW, her movie costume is a least slightly more believable that the glorified one-piece swimsuit that she often wears in the comics. Her DCEU costumes look kind of like the other Amazon armor which is in turn based off of Greco-Roman battle armor, and current comics have followed suit thank goodness.
I apologize for the length of the post, but I really needed to make my thoughts on this clear so that there's no confusion.
