This is a good question! I've had some of my Current/Elliott jeans for quite a few years and they're still in great condition. I also think Rag & Bone has some great quality jeans. Levi's always has some great quality options. In general, I'd suggest looking for jeans with less spandex as they do tend to lose shape, also try not to wash them too frequently. Hopefully someone else can chime in here.
