Which tailor was that?
I have been told that waxman on parc is good although I haven't gone myself. I would not recommend le planche a repasser, I was recommended to them by someone who I trusted and was very disappointed they ignored my request to have a repair darned and just went over the whole a bunch of times with thick thread and I had to bring back something because the seam they resewed was not straight and therefor buckled. They apologized and did the repairs for no charge but still. I also normally go to alterations mike because 75% of the time he does great work and isnt super expensive, but again I have been disappointed with some results and when I bring them up to him he makes some excuse.
The thing I have noticed about tailors here is that they just go ahead and do whatever they think is best and then surprise you with something you didn't expect, lack of communication.. Maybe I am going to the wrong people but I have yet to find anywhere that I want to return to consistently.
