The theory suggests that hemlines on women's dresses rise along with stock prices. In good economies, we get such results as miniskirts (as seen in the 1920s and the 1960s), 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.
