Depending on when in the Middle Ages Crussaria is supposed to resemble elaborate dresses and things like that might not be accurate. Up until like 1400 men and women basically wore the same thing (a tunic). The only real difference was that typically female tunics were ankle or floor length (hence dresses) and typically had sleeves (guys went sleeveless with an undershirt usually). So if you really wanted to you could make another tunic-y model for the female model (sort of similar to what's in the "archer" model) and that would be pretty close to accurate.
Of course the further you go into the Middle Ages and the closer to the Renaissance you get the more elaborate the female clothing gets and then something like that wouldn't cut it at all. But I think most people wouldn't know any of this at all. The only reason I know any of this is because I am taking a class called "Violence in the Early Modern Period" (which is about 1300-1800) and we started off talking about basic life back then.
