The higher the hemline, the better the economy looks - or so theorized Wharton School professor George Taylor back in the 1920s. The indicator has been strangely reliable over the years, and after poring over the hemlines from New York's just-completed Fall/Winter fashion week, Business Insider says that they are indeed going up.
The BI Hemline Index is calculated by measuring hem length as a percentage of the length from floor to waistline. The shorter the hemline, the higher the index. Overall, average hemlines in 2012 registered a 44.38 on the index, up from 35.04 for the Fall/Winter 2011 collections.
