No.

Jeans are mass produced, not only because everyone(almost) has or wants one, but because they do not need to have a special measurement to fit you. Yes, they have measurement but a handsewn was made for YOU and possibly for your kids or so. Plus I don't think they make jeans like they used to(not that I could possibly even know) but I don't think the quality would be the same. The only one that would have chance to be mass produced, IMO, is the utilikilt as they are sort of the jeans or extreme casual side of the kilt. For example the worker model, perfect for outdoor work and look bad. If the utilkilt could be mass produced then I'm sure the price would lower significantly.
