He probably imagines that they can 3D-print the shirts.

If I remember right from talking to a tailor, collars, cuffs and buttons are almost all of the construction effort. If the idea behind "standard" configurations was "We can make these up in bulk in advance and then just add them to the shirt", this guy has even less clue about how to make a shirt than I thought.

It's kinda the point of "custom"-- it doesn't get thrown together from pieces and parts.
