clothes, clothes physics and clipping on 3d humanoid models.

So I been importing Daz3D models into unity and sometimes the clothes clip when animating and sometimes even in the t-pose. My question is how do i fix clipping on clothes and if I can add cloth physics to them at the same time. I would actually just be satisfied if I could animate the character around w/o clipping on clothes. What do most people use for animations? I’ve tried mixamo with varying degrees of success, characters wearing non-flat shoes(heels) often come out with warped feet. I’m not opposed to learning how to rig characters on my own and I still gotta learn how to bring down the poly count on the meshes from Daz(I tried in maya and I kept getting weird errors). Any help would be appreciated.

What would physics do/add to a character that is wearing a skin tight suit?

  1. I never said I would use the given model the clipping occurs on more than just that costume. Even then there are parts on it that are loose that you just can’t see.
  2. I know it’s possible I just don’t know how to do it, but for a costume like this—>
