When World War II ended and raw materials were available again, Levi Strauss & Co. leaped back into heavy production to meet the growing post-war demand. Slimmer fitting, with no extra details like the cinch or suspender buttons, this was a jean that was ready to rock and roll. The watch pocket rivets came back after their wartime hiatus and the Arcuate was stitched on the back pockets again, after being applied with paint throughout the war. But it came back in a different form: thanks to new, double needle technology, the famed double arching stitch was now uniform in size and design, no longer subject to the skill of the individual sewing machine operator and her single needle machine. The Red Tab with its capital “E” had never gone away, thanks to its status as a trademark. The red selvage, 12oz. Cone Mills denim was still the bedrock of the jean, as it had been for nearly two decades. By the end of the 1940s Levi’s® Jeans were aimed at the new, emerging middle class. The 1947 501® Jean was the jean of a new generation.
