Thanks, but not really any competition...:)  (If I only had time for everything I had in mind)

Boom!! Got it working! I guess I was tired last night and neglected to switch from "Split" to "Keep Vertex Order" while importing OBJ into Blender (specifically that the skirt has some disconnected mesh, which is not so good by itself though).

Nice work! Looks like my Morph Cloth Line is going to get some competition ;-)

I have not yet tried to do hair...I watched a tutorial once but it seemed to be a tedious process to create all the layers...but that sounds like a really cool idea (i.e. creating hair morphs).

No real secret...use the work flow as detailed earlier.
1. Created CC Cloth item using the usual work flow (in my case in Anim8or and then rigged in Blender)
2. In CC added clothing from step 1 to CC character
3. Pushed CC character to iC7
4. Activated Morph Creator on the CC character
5. Selected just the clothing and used Morph Creator's Export to export (as OBJ) the selected item (do no include the character)
6. Created my morph based on that Morph Creator reference obtained in step 5
7. Applied morph created in step 6 in Morph Creator
8. Pushed character back to CC to save clothing. Note: In CC the morphs won't show up but they are still retained (saved)

I believe that getting the OBJ "reference" from Morph Creator (and using that to create the morph) was the trick that allowed me to avoid the distortion that I was getting earlier and also any shifts.

Couple of things to note:

1. The morphs should be basically limited to changes along the same bones (as was mentioned earlier) because of the weight painting
2. When morphing, for example, the length it is likely that you will get poke-through at some values. To address this I created a morph that is a slightly larger version of my clothing and called it a Fit Adjustment. When poke through occurs, typically it can be eliminated by applying a bit of the Fit Adjustment morph. You can see this idea at the end of the following video: https://youtu.be/BDhaWs0rzQ8

There is a thread started by AncientWire about transforming a skirt so figured I'll try. But I cannot get it working. Those slight distortions are hunting me.
I saw you managed to make a substantial morphs with skirt length, looks very nice. So what is your secret Lord? Did you use Blender? Any specific OBJ import/export settings?

That's great! Still did not have a change to try. But now I am thinking about getting hair morphs. Like for combing for instance.
Most of the hair (the top part at least) are at 100 influence of the head bone. So moving it would be quite possible without distortion.

Well that is good news! Glad you got that working.

Finally managed to get a working morph without distortion...

1. I imported the clothing into CC2 using my usual workflow.  
2. Pushed to iC7
3. Opened Morph Creator
4. Select clothing
5. Export selected as OBJ
6. Use the exported OBJ to make the morphs 

The odd thing is that I am fairly sure I tried this before and it wasn't working correctly. I guess, when I tried it last time, I must have selected the wrong file to use as the morph import.
I still have no idea what causes the distortion but at least now I was able to get the morphs working without inducing the distortion :D

It might work for a simple morphing, where the mesh offset in relation to the respective bone is minimal. But remember, the cloth is weight painted.

While I didn't consider that yet...agreed. The morph I am working on right now basically keeps the cloth in relative relation to the bone just pushes it somewhat further away. I am trying to make some pants which will have a couple morphs to turn then into bell bottom pants (with the morphs providing options where to start the bell effect). In this case it should work.
I think something like shortening the length of a skirt or even rolling up the sleeves a little should also be okay if the starting and ending end with the same bone. For example, rolling up the sleeves to just under the elbows should be okay for the most part because regardless if the sleeves are rolled down or up the bone that contributes the most in the weight mapping would be the lower arm. Rolling up the sleeves past the elbow would, on the other hand, be problematic because the sleeves would be weight mapped to the lower arm but now would be on the upper arm.
Once I get the process working correctly, I will see just how far this can be taken in this state.
