This is a quickie example of a dynamic skirt rig made for Snow Clone Troopers on the TV show Clone Wars.  It can blend between keyframed and dynamic, with the motion of the keyframed animation affecting the dynamic motion to whatever percentage you want.
This technique was adopted to a number of other subsequent skirt/dress rigs.

There’s no sound with the video, so don’t bother adjusting your speakers…
