Brought in a blazer to have the collar shortened. The work was not symmetrical, causing slight bulges in the jacket when I put it on, and the stitching was very coarse. In the end, I had to take the jacket to the tailor at J Press in Cambridge, who was surprised at the poor quality of the work. Jack's might be ok for simple things like sleeve length etc, but take more complicated jobs elsewhere.
Pros: Location; friendly in that low key gruff way that many tailors have
Cons: inadequate work quality
