I wear casual skorts to work for much of in the summer. I don't care to ride in a bike skort, though I have seen a lot of women wearing running skorts this year.

There are several of the casual/dressier skorts (for tennis or hiking?) that I like at REI (Royal Robbins, Isis brands) as well as at Lands End and Title Nine. The Royal Robbins discovery skort in particular is one that I've worn while teaching, traveling, and jumping on a trampoline (though not all at the same time!) and it seems that there's more of a selection in the past year or two.
