In DS you can also get some clothes that were not designed for GND to fit using DS fitting tools. The above images shows fitting Hougyu Jersey Dress 2 to V4 GND. 

When first fitted to GND, there is a lot of poke through with this dress. The first step is to right click on the dress and select "Transfer Active Morphs" at the bottom of the menu. This takes care of most of the poke though, but there is still a little left.

The next step is to add a smoothing modifier. With the dress selected go to Edit -> Figure -> Geometry -> Apply Smoothing Modifer. That takes care of the rest of the poke through in this case. 

If the default smoothing modifier does not fix the poke through completely, you can go to the Parameters tab with the dress selected, under General -> Mesh Smoothing you can adjust the "Smooting Iterations" and "Collsiion Iterations" to try to elminate the poke through.

This does not work with all V4 clothes. It should work with conforming V4 clothes, though it may not work in all cases.

On the right of the image is the Genesis GND wearing the same dress which was autofitted and with a smoothing modifier.
