You need to make certain that you are selecting the correct model in the scene.  If you do not rename the figures, they will be designated with a numeral at the end of their name.  For example, LaFemme2, LaFemme2 1, LaFemme2 2, etc., depending how many figures are placed in the scene.  When copying morphs, select the appropriate figure from the pull down menu; otherwise, you will be applying the morphs from the wrong figure.  

You can either retexture or recolor the shirt in the Material Room, but I have no idea how the material shaders are set up for the shirt.  I would need a screencap of the Material Room to make the right assessment.  Be warned, the Material Room can be very intimidating to a newbie.
