There are no realistic armor designs for women, because never was made any of the kind, soldiers have been pretty much 99% male in all of earth.
And this is a fantasy game, why bring realism into this?
btw I`m not women bashing, turns out I like women, a lot, but this is just the reality of things, women are more comfortable in bikini than FULL PLATE ARMOR
I think we really need to see just how high or low fantasy the setting will be. If it's a high fantasy setting, expect scantily clad women and men with oversized muscles. Low fantasy we could expect something like Mount & Blade's realistic looking armor. I have no problem with either, it just depends on what kind of setting Obsidian is developing.
