I agree that the interesting changes will come out of the made-to-measure world. Considering the difference in comfort (not to mention look!) that properly-fitting clothing provides, I'd be extremely interested in getting a nice made-to-measure suit if I had the sort of job or social calendar that would give me opportunities to wear it... and while I don't expect to ever be in the sort of job or circles that would require a suit regularly, I definitely look forward to an economical, quick(ish) way of getting a nice-fitting suit. Last time I bought a suit I had to wait over a month for alterations to be done at the department store anyway, so if someone can come up with a way of reducing made-to-measure turnaround to a month...
And then let me gets khakis and less-formal shirts made that way too... I buy a lot more of those than suits.
