Relooking at your pics, it seems the problem with that Sim is her skin tone. Some skins will not work with all custom content. Notice she has a very tanned face but when you put her in that pink skirt she has white legs and white body. What happened there? Maybe it's the skirt and not your shirt. ETA: I have not heard of removing normal bump mapping from a mesh, as that has to do with textures and if your machine can see them or not without having to fiddle with Config files (low end pcs). Are you sure it was about bump mapping or did you mean something else? I can't be here much today but maybe the problem is the skirt. Does that skirt change her skin color when paired with a shirt that has not been altered?
