The skill in measurement is an entirely different skill from that of doing the sewing, however. If you had a machine that could sew as well as a human, we could have an army of measurement experts sending them to the machines, which would churn out custom-made suits.
I think the bigger question is how to automate the sewing. If we could do that, I imagine it would make it much more scalable.
I think if we can make self-driving cars we can make machines that can make a suit. The reality is that it's probably cheaper to pay people to do it.
I have a friend who orders custom clothes from China. The quality is quite high and the price is lower than non-custom clothes for sale at Nordstrom's. Who is going to spent money making a machine to do this when the human labor doesn't cost anything?
