In Holland, they make special saddles for skirt-wearers. Instead of the long point that thrusts between your legs and can spoil the cloth (not a problem with a kilt, but it's cetainly not good for an unpleated skirt), these saddles are almost round; it is just as if you were sitting on the front edge of a chair.
Excellent idea.

Martin, in France, where cycles are, alas, no longer considered to be a means of transport by 95% of the population -- just like skirts, that are no longer thought of as everyday wear by all but a very few (M or F).
