As the story goes at Lanvin: Lily had difficulty finding the exit ( so did all the other girls ) as the models get to the end of the runway, it is was all blacked out, and a black box, so from bright lights they turn around and walk towards a dark black box, then when they are in the black box, poor things can't see the wall, so they don't know where the exit on the right is, so a few of them, and sorry got to laugh, walked straight into the wall, like Lily here just did
