All the skirt movement is actually not done with morphs, although it could have been - this is done with bone posing, you won't be limited to the shapes you see here.  Although, since the dress is lowish polygon (7k) you can't take it TOOOOOO far.  Serious tinkerers may want to subdivide the dress OBJ in a modeler and make their own high poly version - the morphs would have to be redone but Dimension3D's Morphing Clothes did 90% of the work here, it can do it for anybody else too.
