You might try clothifying the hip of the dress in the cloth room and running a simulation to get the skirt to drop down in a more natural way.  I've used the technique with the Morphing Fantasy Dress, along with a number of other dresses and skirts. The key is to have a hip area.  You could probably create a hip area if it doesn't have one, using the grouping tool.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
