Black labels I believe are the cheapest of them. I've religiously worn Levi's for the last 12 years or so. Orange labels are usually the better quality, I generally buy secondhand so never know where they come from. They get the denim from different countries which varies the quality, and always printed on the inside tags. Been meaning to check my favorite ones for the region so I can get constant pairs but I forget. I install tile though so I go through jeans quickly (hence the second hand 10-20$ pairs). Recently though I bought a couple pairs(always same size and fit) but they're significantly different in fit. Can't even button them up
