Made in USA Year of manufacture: Probably before 1991 (around 1980-1986) Size Marked: Probably W31L33 Actual measurements: Waist 74cm, inseam 76cm The 501 is Levi's most standard model, with a straight silhouette that will never go out of style. These are denim from the late 80s to the 90s. There are holes in the knees and thighs, and the numbers on both the paper patch and the inner tag are almost gone, so the original size is not exactly known. If anyone can identify the age from this inner tag, I would appreciate it if you could tell me how. The hem length is just right, and the fading is nice, so you can wear them as they are. I also have other denim items for sale, so please take a look if you're interested.
