I got these in a 25 which is also listed as a size 1 on the jeans themselves. The material is nice and stretchy but still denim feel and I really loved the idea of railroad stripe. The pattern was ok but not as nice looking as I thought from the picture. Also the pants just weren't "skinny" anywhere at all. The knees were loose the lower legs were really loose. The hips and butt were ok but not as tight as they should be in skinny jeans. I chose the right size according to Levi's website but unless you have large knees and lower legs/ankles these just won't work (unless you want a slightly loose fit) The inseam on the "medium" is 32" fyi and for reference I am about 5'4" and about 95-97lbs. My waist is about 24.5 but the waist on these pants were a little loose.
