I wasn't always unpredictable. For centuries, I stayed in pretty much the same place: between the floor and a woman's ankle.
But then things changed. Fashion elites called me boring and prudish. Young people snubbed me. They thought I was old-fashioned -- something only their mother would wear. So I started changing.
My given name is Hemline.
I first stepped it up around 1913. I gave them what they wanted: more flesh. I revealed 2 or 3 inches above the ankle. Sure, some rejected me. But I still won over the crowd. And throughout the next decade the crowd would help me win the rest, eventually persuading everyone who first abandoned my progressive shift to lighten up, to get with the times.
