Hemline index
The hemline index is a theory presented by economist George Taylor in 1926.
The theory suggests that hemlines on women's dresses rise along with stock prices. In good economies, we get such results as miniskirts, or in poor economic times, as shown by the 1929 Wall Street Crash, hems can drop almost overnight. Non-peer-reviewed research in 2010 supported the correlation, suggesting that "the economic cycle leads the hemline with about three years".
Desmond Morris revisited the theory in his book Manwatching.
