People asked about my workflow on Cammy's clothes, so here it is.
You can purchase the Marvelous Designer template and the full character model here :
You can find the next part about extracting displacement maps here :
Yes it's overly complicated, but it works. Keep in mind this is aimed at animation/vfx production pipeline, where the meshes need to be rigged, animated and the details should only be generated with displacement at render time. If you're only trying to render a single image or going to redo the topology for real time, it's probably overkill. Most of the time, a quick Zremesher in Zbrush would do.
Feel free to leave feedback, I will try to improve if things are not clear enough
