It certainly is how the MTM pattern is done, but I don't think it's how the "measurer" actually operates. They take the measurements, write them down, and then the person making the pattern lops off the "appropriate" amount. The problem is that the measurer can easily screw up. Why should I even need my chest or shoulders measured when I know precisely how much extra/less I need as compared to the RTW model? If I know that the 39R in the Gibbons fits me perfectly in the chest, why does the measurer have to nonetheless take a tape measure to my chest, introducing the potential for screwing up? If I know that the 40R shoulder width fits me perfectly (which is .25" larger than the 39R), why do they nonehtless measure the shoulder width, a measurement rife with error potential? Why not just ASK ME what my ideal shoulder measurement is? BECAUSE THEY ASSUME THE CUSTOMER DOESN'T KNOW HIS OWN MEASUREMENTS.. This needs to change for MTM to be a better experience.
