The opening of the new Prada store in Los Angeles drew in the LA elite, including Jennifer Aniston and Brad Pitt, Robert De Niro and Leonardo DiCaprio. Prada's new 'epicenter', as they call it, has no door. A vast aluminium wall rises from the floor, sealing off the entrance when the store is closed. Only the price tags are likely to serve as a barrier to entry, otherwise the shop front is open to the street. The Los Angeles shop is Prada's third epicenter, the others are in New York and Tokyo. A fourth is planned for China and epicenters in Europe may follow later.
