Character + cloth

Simply binding both meshes to the same softbody should give you the results you want. No need to write any code.

Keep in mind though, that unless both meshes have identical topology the resulting skin weights will not be identical. It’s just how linear blend skinning works: two vertices will not have the same skin weights unless they’re at the exact same position. Also, using the same skin weights for vertices at different positions will result in garbled deformation.

Yes, they have the same topology and almost the same position. Stockings can't be on the same position as the body. I can bind them both to the same softbody but I can't manually paint them the same way for the parts that needed for the jiggle. Painting method is very approximated.
