Levi's Vintage Clothing 1947 501 Jeans Indigo Rigid - Blue. The year was 1947, and although the war had ended, the nation was much changed along with 501 Jeans. The end of rations allowed for the return of some familiar 501 features, like the watch pocket rivets. Today, Levi's reproduces all of these details using the same 12 oz. red line selvedge denim. This model features 100% organic cotton, non-stretch material, a straight fit, mid-rise, button-fly, five-pocket construction, and a leather patch at the back. Made in Japan. Style Code: 47501 0224.
