I also had a good experience with shirts, which is why I decided to give the trousers a try. And yes, my measurements were also from a professional tailor. But the resulting trouser has (among other issues) been "corrected" to a 15cm shorter outside leg length, so I wonder if a professional vs. an amateur measuring it would have made much of a difference.
