Levi's 559 has always been my favorite jeans for casual wear. They fit perfectly for my size, which is athletic but not huge (huge would be 550 or just very baggy).

Also, the color and subtle shades are as good as the jeans that I have that cost 6 times more. Great jeans, great fit (with a belt), and really great color.

My only minor complaint is the waste seems to have gotten slightly larger for the same size, or the pants slightly baggier only on the top so that they slide down without a belt. This has not happened before and I am the same waste size. I don't know if it is to shift more to the baggy wear the kids enjoy without a belt, or the style is not as 70's with a belt (which is good), but when I wear a belt problem solved and the fit is A+.
