I've had good success with M Kenny and My Tailor. It's definitely not as finessed as some other MTM, but there's not many options in DC. I have used Field English Custom Tailor. The prices were nearly double that of My Tailor for Thomas Mason Silver fabrics and the results only better for the collar and shoulder slope adjustment. The sleeves were a tad too short. Mr. Field has the shirts made at Geneva in NY. Both fit well through the body and arm volume.
