I realize that this thread is old, but I thought I'd share my experience with Brooklyn Tailors. I have three custom shirts that I got from Brooklyn Tailors towards the end of 2011. Daniel and Amanda couldn't be nicer or easier to work with. Throughout the process, they were very communicative and willing to explain why they did things a certain way. Also, they are open to making alterations to their house style without any fuss. When I received my first shirt, there were some changes that needed to be addressed before making the second and third, which were improved upon in the subsequent shirts. I even requested a second visit to the shop after I had washed and worn the first shirt several times to get Daniel's opinion on the necessary changes, and Daniel was happy to accommodate me (when I picked up the first shirt, I tried it on and Daniel made some initial adjustments to my pattern).
While my shirts turned out well initially, the ultimate issue that I've had with them is their construction. I've found the construction of each of the shirts to be sub-par. The shirts are made in Nepal, which in and of itself shouldn't necessarily lead to a poorly made shirt, but I suspect they could have found a better place to produce their shirts. I've had to re-sew buttons on two of the three shirts, and the shirt whose buttons have managed to stay attached has uneven stitching on its hem. The need to re-sew the buttons was not due to poor care, either. I have never machine dried these shirts. I typically hand wash them, and when I do machine wash them, I wash them on the cold water, delicate setting. Given the cost of their custom shirts, I expected better. In the future, I would certainly consider returning to Brooklyn Tailors provided that their shirts are produced elsewhere because Daniel and Amanda provide excellent service, and I think their shirts are designed well. For the time being, though, I might try CEGO for some casual shirts since I've had good luck there with my dress shirts.
