If you want your suit altered, go to other professional. I came to him to alter my Armani suit and pants. He was never in the office when I stopped by to pick up my suit and had to redo alteration of jacket. Bad experience in working with the pants - not only he damaged fabric on pants and refused to acknowledge it, he also charged me for the service he never performed. I'm not sure if he can tailor a suit altogether if he cannot even shorten pants correctly.
This was my first time using Q tailors but I've always heard great things and they proved everyone right! My pants I brought in were 2 sizes big and the legs were like a tent and they tailored them to perfection. I will only be using them from now on!
