Sorry, that was just half the workflow. First step is to produce all needed MT's on the static mesh. Then, you have to transfer the MT's to the original cloth figure. This is where I said using DS with VWD is the easier workflow, but it still might be possible in Poser. I will see if I can transfer MT's using Poser.

Which version of Poser are you using? Completing the transfer technique might also be dependent on version used. I will try in both Poser9, and PoserPro2014 (which has copy morphs tool).

For DS, you could probably omit the Blender workflow, and do it all within DS. I do 90% of my morph target work in Blender, but for this, only DS is needed.

You need to use the conforming figures morph duplication trick; 1) Turn the VWD static mesh into a conforming mesh using the Transfer Utility, and the original conforming mesh as donor. 2) After you have created the VWD conforming mesh with all the MT's, conform the original mesh to the new VWD mesh (hide the new mesh if wanted). 3) Select the new mesh, and one by one, dial in the morphs (which will propagate into the original mesh). 4) Change the parameter settings (unhidden, percent, respect limits, etc. to your liking). 5) Update the assests in the original mesh to permanently save the new MT's. ...Done...

The image below was created by dialing in several different MT's created in VWD for both the hair, and the pants until I achieved the look I wanted. I used the technique outlined above for both conforming objects.
