Levi's 557xx This is the third model from the late 1960s to early 70s. We offer a discount if you purchase the top and bottom set together, matching the era. The back of the buttons are marked with "525," which seems to indicate it was made at the El Paso factory. There was originally no patch. The Levi's red tab is a Big E. I bought this set, along with the jeans, 10 years ago at the same store. I hope someone who will cherish it will buy it. Thank you for looking.
