On a recent Saturday morning in Brooklyn, New York, women and a few men jostled to select from rows of racks of brightly coloured clothes designed in African print.  There was barely any elbow room as people squeezed past each other; and the shop assistants could barely keep the racks stocked fast enough.  The long lines at the checkout registers were evidence people were spending lots of money.  This was the scene at a recent pop-up store hosted by online store Zuvaa.com, which brands itself as ‘A Global Marketplace for African Design’.
