Also if you've ever done a deeper analysis of Lucky jeans, the same exact model is wildly different depending on where it got produced. Different material composition, fit, flexibility/softness (due to the difference in materials), different country it was produced in (and IIRC, it's not even consistent. Mexico is not always 100% cotton for example. There was no discernible pattern)
I try to find products I like and then buy a bunch of them (in case they stop making them, etc) and I wound up making a spreadsheet once after becoming frustrated with the inability to trust the same "model number" means the same thing there.
