I don't think enough good things can possibly be said about the Suitsupply staff. I showed up on a Saturday morning with a suit that I'd purchased from their online store asking about alterations and not only did Zakary and the other staff happily answer my questions, they discussed a few different viewpoints on style, answered all my questions AND got all of my alterations taken care of in just a few hours. When I mentioned that I just happened to be in town for the weekend everyone worked to make sure that I was able to walk out with my perfectly tailored suit just a few hours later.
In short, some of the best service I've ever had and a great looking suit to boot!
