why do you give up so easily?

as far as I can see (so please correct me where I go wrong) you've got three meshes, or sub-meshes in one large super-mesh, and they are not connected. Right?

The belt (sub)object will rest on Vickys hips in the sim. The black thing is - in real life - attached to the belt, but it's not attached from a mesh point of view. And when the belt moves and deforms, the black thing should follow.

Now when you put both the belt and the black thing in one sim, there is no way to do that because the black thing is not a decoration of the belt (but cloth by itself), and you can only constraint vertices of a piece of cloth to an figure which is not in that sim. So, the black thing should be constrained to the belt, but they should be in different sims. The same story holds for attaching the red thing to the belt. The black and the red thing are not stiched together, and so they can be in the same (second) sim. Check self-collission in that case.

The belt-sim should be created first, then you create the black & red sim. Then you run the sims in that order, as the movements of the belt is leading. Or, the menu: Animation > Recalculate Dynamics will run them in the order they are created.

Does this work?

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
