It's not even that. Cheesecake can be great when the characters are fully aware of it and are consciously choosing to wear that sort of clothing for their own reasons; see also Circe in The Books of Magic, Zatanna and others such as The Whip in Seven Soldiers, and Silk Spectre in Watchmen (although that's more Sally than Laurie, who gradually realises how horrible and degrading her outfit really is).
But this, this is characters being poked and pushed and squeezed into sexual positions without realising it, for no real reason - e.g., that sixth panel, above - reducing them to nothing more than sex dolls, and in Dini's case weakly characterized ones. Mike Deodato was guilty of this throughout his Thunderbolts run with Ellis; sometimes it seemed as if the female characters lacked any vertebrae whatsoever.
I know this comm is a regular Morrison-trashing haven, but I'll say this: Final Crisis had strong female characters who each played significant parts in the story; any of the onesin revealing outfits or smutty poses were shown to be under the influence of Darkseid. I bet that by the time this series is cancelled, it'll have had more sexism in three issues than anything written by Morrison in the entirety of hi's career.
