From 3d printed clothing, the obvious next step should be to have your phone take a 3d scan of you, and send it to the clothing designer to print it to your actual body size and shape. We could have truly unique sizing (none of this S/M/L/XL stuff)!
Edge case: people who are in the process of changing their body size/shape. Growing children, people losing weight, people gaining weight (they're out there), will all occasionally want to buy for where their body is going to be in the future, not where it is now. How to accommodate them?
I'm sure models predicting how their body changes (based on various parameters and previous scans of the particular person and other people) could be built, allowing to optimize for longest time period of "decent fit" at the cost of "perfect fit now".
Yes, and people have been chasing that Grail for decades. It's always right around the corner. (Despite what another poster said, it IS being pursued commercially. And unobtainable so far.)
