"At the moment we are working to get rid of the gender lock for bunny suits for men."

[Adire]

So when the male bunny suit comes out they'll be lore friendly once they're glamoured over armor then. Problem: solved.

No, problem not solved, because it breaks the aesthetic of the game because crossdressing is pretty much unseen anywhere other than on players. If it were rampant among NPCs, maybe you'd have an argument. But it's not. There are NPCs in skimpy clothes, some even that do battle. Like the Miqotes in Thanalan. Some of the armor itself that drops is skimpy (like the armor that drops from Darkhold).

Besides, crossdressing is an entirely different thing from skimpy dress. An underdressed warrior is not the same thing as a crossdressed warrior, they're seen by people differently. One is wearing proper clothing for their gender, the other is not.
