The gasp factor at Prada’s show tonight was the vastness of the new multipurpose performance space at the Fondazione Prada she has opened. We sat on inflatable Verner Panton stools and took it all in: the stadium seating at one end; the cavernous hall; then the fact that the floor was marked out with grids of geographical coordinates denoting the exact place in the world each one of us was occupying. “We wanted to introduce life to the Fondazione, because sometimes art is not enough,” said Prada.
