Any decent tailor will make adjustments with each fitting, sometimes all the way to the end. The problem isn't that it needed adjustment, but that the tailor didn't seem to recognize that it needed it. How many fittings did you go to before he felt it was finished? There's no magic number--you go to as many fittings for adjustments as necessary. Sometimes it's three, sometimes it's six. As long as you're satisfied with the finished product. If I may ask, what city was this tailor located in?
