Maybe asking robots to do the human thing is not the right approach. Just like dishwashers don't do things resembling how humans approach the task. Which implies the clothing would have to change somehow. Is that even possible? I don't know.
I think the loom is already the dishwasher here, where sewing is collecting used, unordered dishes.
I think these tasks need a deeper understanding of what's there to handle. Prediction how things will behave and adapt intelligently if they don't. E.g. spontaneously using your pinky to stretch away the fabric getting in the way. You need to understand the meaning of the seam to manifest it, even out tension, redo some part, ... Non petrol based fabric has imperfections and variances.
I think you need general purpose, human-level AI to sew a good jeans.
