My reading of this was that the fourth dimension was time. First, a loose dress is 3D-knit; then, when the owner buys it, it's possible to apply heat to cause parts of the fabric to tighten up, overall making a bespoke fit without significant manual labour.

I'm not entirely sure how much labour is saved vs making it custom cut from the start, having to stand in the reach of an industrial robot and get blasted with a heat gun doesn't seem like a great customer experience... presumably all the relevant measurements had been taken ahead of time so a tool-path for the robot could be created

Seems less about saving labor and more about proving technology.

You could take this concept a step further and 3d-scan the subject body with a laser, then 3d print a model, and the clothing draped on the model and heat-shrunk (rather than using a software to decide where to heat shrink and how much)

It’s shrink-to-fit denim, with a 3d pattern. Instead of wearing your dress in the bathtub, you hang it up and a robotic arm blow dries it
