It is very simple: Export the dress with the V5 morph, conform the dress to Genesis and dial V5 and you get the following as shown in the picture

That is a zero pose and it shows here the back of the dress.

The front has similar issues

Eww. Hard to reconcile Rand's statement with that screen cap IMHO - and Genesis's skin seams don't look pretty there either with the wrong UV Set exported for that texture (so you've got two major issues highlighted in one image!).

And now we wait...

 

The UV issue is a known issue - it exports the V4 UV mapping. If you apply a V4 map it will look good. I just did not bother to do that to show the problem with the dress
