At least five benches collapsed as people took their seats at the Rue Cassette space of theBalenciagashow. Too much soufflé last night, maybe? No one was badly hurt, just startled, but before another one could go crashing to the floor, a voice came on the loudspeaker and asked the audience to stand. It sort of felt like church. Which was fitting; the fashion set has long worshipped at the altar of Nicolas Ghesquière.
