The skirt length echoes the economy. When we are doing well, the skirts tend to be longer. When the economy is in trouble, the skirts go up. Expect to see the skirts get longer when the economy improves.
Yes, I've seen that trend in history. Thin skirts with minimal fabric during the War and then big poofy skirts afterward.
