disable autofit for self made shirt

Illidanstorm

I made a shirt for G3F which would fit perfectly but autofit destroys it by moving it around. I made the shirt in marvelous designer and exported it as obj and go to edit > rigging > convert prop to figure to fit it and then set the compatiblity base to Genesis 3 female but autofit still asks me how it wants to fit it. What can I do to avoid this autofit?

Import it and use Edit>Figure>Transfer Utility to rig it.
