Okay, I am a bit confused. Did you make the polo shirt, that is the mesh? Or did you take an existing mesh, say one a Polo shirt you already had in Poser for Mike 2 and just make a new texture for it? If you are using an existing polo shirt, that it should be set up already to work right (cr2 and all that). Load M2 into your scene, then find the polo shirt in the library and load it by double clicking on icon - or else on the double check marks at the bottom of the library. When the polo loads, select Figure:Conform To from the menu tool bar across the top of your Poser screen, and when prompted select the M2 figure, this will probably be listed as Figure 1. Poser will conform the polo to Mike. Next open the Render:Material from the menu bar (or CTR + U hotkey). When the material editor opens, you can load the texture you made in place of any that loads by default. Use the Texture Map Load button.
