My reservation about bespoke or mtm (as opposed to rtw) is that you have to effectively act as your own designer. Aside from the issue of whether your judgement is any better than that of Tom Ford or Helmut Lang or even those of their minions, you need to be able to communicate your wishes effectively, and often forcefully, to your tailor. And, as MPS points out, you have to do your own quality control as well. With prestigious tailors, they have at least their considerable reputations to protect, and you have some guarantee of satisfaction. Moreover, the more famous English and Italian houses have distinctive and well-known silhouettes. It you want a soft shouldered suit with some high arm-holes and some waist suppression, you go to Kiton. If you want a highly structured shoulder with a longer jacket and waist suppression, Gieves and Hawke With an unknown tailor overseas, on the other hand, getting a good tailoring done is often a struggle. My point is, when you walk into a retail store, you can have the satisfaction of seeing a suit, trying it on, and finding out immediately whether you love the suit or hate the suit. And with very minor alterations, you know that that suit will fit nearly perfectly. You don't have the headaches (should I have taken the tailor's suggestion for an extra half inch on the chest or not?) or the long wait for something that is potentially a few thousand down the chute. I know that I'm not going to get any love here, but I think that unless you have a very peculiar body, in general, RTW is the better way to go.
