Believe it or not, I (as another female player) like this Dís, too, and the reasons you listed (easy to disguise, wouldn't stand out, all that), are exactly why I think we need properly playable female dwarves now. That said, I don't think this is something that can just be met in the middle. It's either one way or the other. Consistency is important, and so is variety. If Dís can have a feminine build, our dwarves should be able to, too, and whether that build is hidden or not should be up to the player. The male "disguises" (
Dísguises?

) should be made, by choice, by players using the actual modest, masculine cosmetics in the game. When you put the bare-chested cosmetic on our current dwarves (note that this particular cosmetic's effect should be altered for the new female dwarves for obvious reasons), the argument that they're just hiding those breasts under clothing goes right out the window. That is a male chest. Or do dwarf women change sexes when they take their shirts off?
So again, one way or the other. I like the Dís, but if you can't offer that same body type to playable dwarf women, you shouldn't give it to NPCs.
