Actually, this is precisely what happened to me a couple years back. I was shopping for a suit, and have found a brand-name pre-made suit costing about $1000 (that's converted, I don't live in the US); then I simply crossed the street and ordered one at a tailor. I had to wait a week or so, but the cost was half the first one. (Of course, there were less expensive pre-made suits available too, but the price of the cheapest one I found was only about 15% less for than the tailor-made one.)
