@RobynsVeil: I am with you there. Conforming just does not do the trick for end result unless it is for skin-tight underwear. I am even more lazy and use Marvelous Designer as simulation engine. This allows me to use the original definition with flat cloth state for strain zero and original fabric properties definition.

Yes, I know about the MD startup price tag and I sincerely hope someone in the Blender community will pick up the bridging possibilities:

• Fabric propeties and fold lines come in the metadata files (.xml)
• Fabric strain per facet is in embedded in the geometry as exported.

This should be enough to set all the garment related part of the simulation parameters in Blender.
