Pleat Swing Physics?

[george7]

Oh, I'm sure the Wizard already knows the answers. however, I think the pleats would have to move in more of a wave forme than individual pendulems... like a slinky to some degree.
That is not so important to me at this point; it's that slight tendency toward keeping it's shape while remaining very flexable that I'm pondering...

Pleats move as a group of pendulums. If you watch a kilt from the back, they all sway in the same direction at once.

Your slinky perception is the sway in the forward direction of motion. That's due to the fact that the motion of walking isn't quite constant.

It is more like one pendulum adds to the next and the last pleat sees the most movement.
