@FatCat: I don't think the real issue with mailkinis is that they offend women, even though the thread has deviated to that point, the real issue is that "impractical" doesn't begin to cover it, why call it armor if it really doesn't protect you, like someone said, mailkini puts the "cleave" in "cleavage". However, if you take the time to explain that the protection doesn't depends on the actual armor but on some kind of spell it has or an amulet, well, then it isn't much of an issue.
I have to disagree on this point. If a woman is dressed in a mailkini but the protection comes from some magical ring, why is she wearing a mailkini? Why not something lighter and more practical like a linen shirt and pants? The mailkini, even though it isn't a complete armor set, weighs a lot more than a shirt and pants. For ease of movement, a warrior would go for the lighter option (with protection being equal as provided by the ring).
In my novel, I apply practical armor to all genders. This is not to say that some of my characters won't use their sexuality as a weapon itself, but not every woman is there for eye candy.
