I've seen that ghostly effect before. It could mean that Poser is trying to superimpose your group-material on the main cloth. Actually, texturing the entire shirt will work better, and it's not hard once you get used to the steps. You need UVmapper (the free version) and a decent 2D program like PaintShop. There's a tutorial on the UVmapper site http://uvmapper.com/uvmaptut.htm that will take you through the stages pretty well.....
