There was recent discussion on the net about slips riding up.  I have a
theory that this is not static cling, but rather a purely mechanical problem.

Imagine you are rubbing your hand along a chain-link fence in a diagonal
direction, say from north-west toward south-east.  Your hand will slide
along, granted with a bumpity-bump, but it will slide.  Now move in the
opposite direction.  Your hand will tend to catch.

Now imagine a weave similar to a chain-link fence, shrunken in scale to the
weave of stockings or the fabric in a slip.  In a microscopic sense, the
loops of fibers might look like this:

         / /
         / /
         / /
         / /
stockings  slip

The motion of the stocking against the slip could create a ratchet-like
action and push the slip up.  If the stockings were worn
inside-out, the loops of fibers would look like this:

         \ /
         \ /
         \ /
         \ /
stockings  slip
(inside-
 out)

Now the ratchet-like action would not exist, and the stockings and slip
would slide past each other.  There might still be static cling, but the
mechanical interaction would be stopped.

If *both* the slip and stockings were turned inside-out, I suspect the
result would be to push the slip down as the wearer walked.

This is just a theory.  I have no personal experience with these garments.
But if any of you want to try the idea out, I'd be interested in having the
results reported on the net.
