There are some online companies that make shirts to order. Two that are popular here are Proper Cloth and Luxire. Just find a shirt that fits you the best, take its measurements, and tweak them to how you think they should be. You don't have to go in to a tailor, just send them the measurements. In the case of Proper Cloth, you can have your first shirt altered for free once if it doesn't turn out quite how you want it.
