Minor Animating Issue

I've recently been working on a dwarven sorceress model for the War of Zul'Aman project and I have run into a problem while animating it in 3dsmax 4.2. I have the entire model animated with the exception of the dress. I cant seem to figure out how to make it move along with the legs durring the walk animation (similar to the spellbreaker). I've used the "select and link" tool to attach the rest of the model together, but I dont know how to attach the dress mesh to the two parent leg bones. *sigh*

So here is what it looks like so far. Any suggestions on the appearance are also welcome.

Divide the meshes into serveral piece meshes and maybe use helpers as well to make the dress move more smoothly
