A solution looking for a problem
Or as Dr. Malcom would have said, "Just because you can, doesn't mean you should".
When I was a teenager many moons ago a pair of Levis jeans would last years of hard wear and weren't too expensive. Now they are way too expensive, seem to last no time at all and are made in sweatshops located in third world countries instead of the US. They do have loads more tags sewn on the inside that need to be clipped out.
There might be niche applications for doctor monitored health reasons. Spacesuits, firefighter turn-outs and some other specialty wear could be good targets. It might even be that sensors could pick up on signs that a seizure is imminent and could warn the wearer or their care-giver. For day-to-day wear made to a price it will last a couple of time through the wash or need to be specially cleaned at a much greater cost.
I'm already looking at making more of my own clothes. It takes time and isn't less expensive, but I can make things fitted to me out of much higher quality materials so they'll last a long time. I've found a couple of good YT channels where the vlogger finds quality clothing at thrift stores and shows how to mend and alter them. The Aspiring Gent found a nice wool suit for $20 and tailored it to fit like something costing closer to $1,000 (I have a thousand dollar suit and it IS very nice, but I can't justify more of the same). Adding electronics seems like a good way to limit the lifetime of a garment and cause other issues. Trying to alter something with wires running through could be quite a chore.
