Jimenez makes a good argument there, and it's similar to the stance
Gail Simone takes with Powergirl and her boob window:
But I have a feeling that the argument doesn't really hold up when viewed over a group of superheroines, because the suits are supposed to represent something about the superheroes and -heroines. Superman's costume is colourful and meant to be highly visible. Batman's costume is meant to intimidate and to meld him into the darkness of the city. Nightwing's costume plays up his acrobat past. Aquaman has fish scales and gloves like a fisherman, and colours of the sea. The original Flash costume had lots of running and speed imagery.
But just about every superheroine costume has "sexy body" as the defining characteristic, are primarily drawn by men, and for a long time primarily for a male audience. That's not a good place to start to express female sexual power. There are a few exceptions of course. Supergirl's first costume was basically a miniskirt dress, but it appeared just as they started to become fashionable, and her appearance was more of the wholesome girl next door than sexy. Powergirl's boob window works because it sticks out even for superheroine costumes.
There is also the factor that the uniforms has to make sense for where the character comes from. Wonder Woman's battle skirt clearly fulfills that purpose, the bathing suit not so much. (I note that Darwyn Cooke experimented with a battle skirt for Wonder Woman already back in New Frontier.)
