Hi everyone, I am trying to smooth out this robe... I am using the Edit Mesh > Sculpt > Smooth Mesh option.... and after smoothing out the mesh it breaks away whenever I apply any animation.

I tried smoothing and then baking it... and still it breaks apart (see attached pics). Any idea what step I am missing here to make the Robe look fluid and smooth??
