Ahhh, I know what you want now.

Frank is right, you can't do that with the clothing for the Millennium figures like Michael, Victoria Aiko etc.

However if you want clothing that is actually part of the figure, you can use "second skins" which are skin textures textured so that they look like clothing.

Here is a link where you can find some FREE second skin textures for Michael.  You apply them just like you would a skin texture, using the Pose room. There won't be any files in the Character folder like you would find with regular clothing:

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
