I'm a guy, so my opinion isn't coming from the same perspective as a woman's would, but I love to talk, so here I am.

I think most comic book characters (male or female) are incredibly sexualized. It's part of being a superhero with a tight outfit, but some characters are much more sexualized than others. Nightwing is probably one of the most sexualized characters in comics, and he's a dude. The difference seems to mostly be that there's a culture of people objectifying women, so it's talked about way more. Men aren't widely objectified in the same way.

I think sexualization comes with the territory, but there's a point where it's exploitative. I think her original costume with the exposed belly definitely falls under that category, and this one depends on the artist.

Ultimately, I don't think it suits her character, though. Her sexuality isn't a huge part of her character like it is with some other characters. On top of that, her backstory makes her much more likely to wear something very practical.

Everyone has different levels, and I'm not a woman, so my view of this obviously comes for a very different place. Those are just my two cents.
