Textile knitting machines have been digital for close to 100 years (old ones used chains with risers that would change the gears of the machines to change the knit). For simple garments, there's a completely automatable step that makes the majority of the piece, but then there is often hand-sewing to assemble the final product (e.g. sewing sleeves into T-shirts, seams into toes of socks, etc…). Trick is developing the robotics to manipulate it so this can be automated. It doesn't have to be fast (like a factory needs) if you're making stuff for yourself. There's a whole ecosystem you could build around downloadable designs, consumables, etc...
