Ow wow. I am now convinced that this whole thing was a coding screw up…or a placeholder. No way did they give her a male body on purpose. Could be same for dreadful eye make up too.
It's possible she is supposed to have a "cultist leader" armor and Larian doesn't want to spoil it yet. Considering they won't even let wizards have their robes.
Someone has datamined several armors not implemented in the EA yet, and these include cultist robes.
