I'm reminded of an experience some 16+ years ago, when as a television director, I was assigned to make a non-broadcast programme (for BA) about the last-but-one "stripy" uniform for crews.
Unfortunately, at the time we made the programme, the real print materials had not been received by the uniform makers, so some bright spark at BA had a load of uniforms made up which had poster paint (or similar) stripes painted on to the white fabric (shirts, blouses, ties etc.). At one point, we had a short scene where a group of cabin crew had to walk from a LHR pan, across to an aircraft. So far so good. Unfortunately though, it started to rain. Within seconds, all of the "models" resembled an explosion in a paint factory.
