I am so funny about skirt length. I swear. Every time I wear a long skirt, I go out and see someone in a mini and think, gee, I would be happier in a mini, wish I'd worn one today, I have great legs.
But every time I wear a short skirt, I go out and see someone in a flowing long skirt and think, gee, I love that elegant look, wish I'd worn one today, why be stingy with the fabric.
Of course, when I wear knee-length, which I do most of the time, I feel skirt envy pulling me in both directions at once. Must be a perversity of human nature to want whatever we ain't got at the moment.
