Whenever a new character needs to get introduced, they make an effort to have it not be another "Straight White Male", which is what 99% of all superheroes are.
The new Question is a Hispanic woman and a lesbian.
The new Atom is an Asian man.
The new Blue Beetle is a Mexican teenager.
The new Batwoman is a white lesbian.
Furthermore, DC decided that Supergirl will no longer incessantly flash her panties at everyone and everything, as was her normal custom.
And now Wonder Woman is putting on some pants! Now the Wonder Woman costume change will probably get changed back. Drastic costume changes rarely take. However, I think she really needed a change. Something less drastic might have been to have her bottom come down to halfway to the knee, and give her some tall boots. Then have her top cover her whole chest and her shoulders. Her bracelets can then cover her entire forearm, and give her a sort of Spartan cape.
Anyway, I give DC props for trying to grow comics up a little bit at a time.
