True that it depends on which Savile Row tailors we're talking about. I'm not criticizing how things are done or to generalize about Savile Row. Just explaining that outsourcing some things isn't a sign of bad quality. And yes I have some examples, all my Savile Row suits had trousers made somewhere else than at the premises of the tailor. That being said, I'm not mentioning any of them as it's not the point here.
