As the article points out, the Justice League movie has an essentially all male executive team as well as a male costumer. There’s presumably also a Creepy Marketing Guy (or even a small army of them, seeing as this is a DC/Warner Bros production).
No matter who to blame, this is just self-demonstrably shameful.
What’s really baffling about this is that Zack Snyder and same costumer, Michael Wilkinson, did manage to create a fairly decent (fantastic by comparison, but certainly not without it’s faults) female costume design in Man of Steel, as worn by the glorious Faora-Ul:
Most of the high end production staff from Justice League also contributed on Wonder Woman. So that leaves us with several equally terrible possibilities:
Someone with executive power literally saw the early sections of Wonder Woman and decided that what it needed was more women’s body on display so asked for “sexy versions of that”
The executive(s) in charge have been starting with “playing it safe” to build hype on the initial movies, and now have concluded that since those were a success they can throw female characters and fans under the bus in favor of their own puerile fantasies
You may notice a theme of this being an executive with very poor judgement, and as much as a suspect otherwise I really hope it’s NOT Zack Snyder. Because if it is, this does not bode well for the future:
