Nothing matters more than fit. I've had tailored suits that were tailored by retards (or more likely, tailors who have no idea how to fit a fit man) and off the shelf jackets that fit like a glove.
If you're getting a custom tailored suit, ask to see their other work and see if the style works for you. If it doesn't, go to another tailor.
