Introducing Levi's® Vintage Clothing, a meticulously crafted collection of authentic reproductions based on garments in the Levi's® archive and finished with faithfully reproduced details. Due to a scarcity of materials in the 1940s, the WWII-era 501® featured a back pocket arcuate that was painted rather than stitched, unbranded buttons and concealed back rivets. Made of indigo-dyed red selvedge from the legendary Cone Denim® in North Carolina, these are prone to crocking, or color transfer; we suggest you wear (and wash) them with dark colors. Note that rigid denim will shrink to fit: We order true to size and spot clean ours, but if you plan on washing yours, be aware that the waist will shrink 2" (approx. one size) and 3" in the length. Button fly. USA. Machine wash. Cone Denim is a registered trademark of Cone Denim, LLC, a subsidiary of International Textile Group, Inc.
