Model Number: 500 series Model Name: 501 Silhouette: Straight Features: Red Tab, Paper Patch Stains, Tears, Odors: None This is a 90s 501! The paper patch indicates a W32 L38, but it has been cut off! The button back is 552. Made in an American factory! Based on the inner tag, it's a 1992 model denim! I bought it at a used clothing store for about 10,000 yen! I'm selling it because I haven't had many chances to wear it!
