I echo Marc's comment about the overstated importance of the cutter. It really doesn't matter how beautifully cut something is if the tailor who then makes it up makes a pig's ear of it. Equally a talented tailor can recover a badly cut item to the extent of virtually redrafting it. The key skill is in being able to fit an item well and mark it up so the tailor understands what needs doing - and that is sadly lacking these days.

I wonder if there is something peculiarly English about the Savile Row approach. There is an attitude that says that the important thing is for the suit to have a particular look and everything else is secondary. In fact if the finish is too good or too perfect then it would look as if you cared about your clothes more than you should. This attitude is represented by a friend of mine who once said, "It's not important that you  wear a suit, what is important is that you wear it badly". I hope I'm a disappointment to my friends.
