As one of the world’s foremost trend forecasters, Lidewij Edelkoort has advised companies ranging from Coca-Cola to Lacoste on everything from how to communicate with emerging youth archetypes to how to expand into new fields of interest outside of fashion. But perhaps her most well-known effort is her production of trend books—under her Paris-based company, Trend Union—that forecast market movements two or more years in advance. In the textile industry, her research has been used by fashion houses such as Armani and Prada.
