I checked the figure and it appears that magnets have not been used.

For the morphs you'll need to search for the various morph dials and set their values to zero. Only difficulty here is that DAZ have set all of those dials to be hidden. Probably to prevent users from hurting themselves.

For the amount of poke through you may just want to use a magnet to expand the cloth slightly at those points. Or use the Morph Tool. I'd probably use the morph tool.

Or you could use Wardrobe Wizard to create an Inflate morph over the entire model.

Hope that gives you some pointers to a few of the options that spring to mind.
