I am assuming that you are trying to transfer rigging from G3F (please use the proper naming to avoid confusion) to a custom made dress. Or does the dress belong to another figure? Judging from the panel settings, I would uncheck the Face Groups, you really don't need it with the dress. Take a look at Content Type at the bottom and see if there is a selection for appropriate for the clothing. Otherwise leave it blank. After rigging transfer, save the dress to your library, delete it from the scene, then reload it it G3F. Allow autofit to dress the figure. If it doesn't fit, check if there are any active morphs causing poke through. Those might need to be transferred also.
