After you've chosen the material(s), they'll then have plenty of magazines for you to sift through for design ideas. All this can be quite overwhelming too, let me warn you. This might take another 30 minutes or so. By the way, the time delays I'm referring to are in reference to you, the shopper, not them. They are more often than not extremely patient and helpful. Usually it will be us, the shopper, who'll waste hours pouring through catalogues of materials and magazines. And it's very easy to do, trust me. Then they'll measure you up which is the quick and easy part. Ok, That's day one.
The next day, if you're very lucky, they'll have a rough cut assembled for you to try on as a loose fit. Here they'll make any final adjustments to the style or the cut. That's day two.
Then by day three or four, the final suit or piece will be ready to take home. This was my expereince when I had two suites made. Of course, all this is dependent on the complexity and quantity of things you want made. So I don't think dashing in and out inside of a day is enough to get things done.
A final thought: don't bother writing down when you're there any material codes for next time. If you come back to the same tailor a year later, they're likely to have all new materials and catalogues. That's why you need several hours up your sleeve when you get there to choose everything. When you get there and go through the process, you'll undersatand exactly what I mean.
