Which model Levis? It really varies a lot. Sometimes it even varies depending on the colorway, I've found. Best if you can try on in person, or order from somewhere with free returns. I've tried a bunch of their newer low-stretch cuts in the past year. The 501c is much lower rise and larger-waisted than the traditional 501 and I had to go down a size, but I wear them more like a skinny girlfriend fit, not the loose fit they show on the models. The 505c and Wedgie fit (terrible name, nice pants) are both true to size, I find.
