As we know, the game displays only those parts of the armor that are both on the 3D model and drawn in the texture.
The Castaniks have breasts, Elins too, the Elves do not have breasts, there are holes under the texture, and the texture of this suit, like many others, is the same for all classes. So we get that an intelligent mod will not work out of this suit. I don't know how to finish drawing 3D models in blender or 3DStudio and few people can.
The author did Elin, but did not think about other races and did not check the correctness of the display.
