I have 2 pair of Levi 505 that recently had a belt loop pull off on one end. That should be the strongest stitching there. Each pair has a hole where the end of the loop was stitched to. I agree about the clothes not lasting as long as before. Some shirts I see at Kohls dept store are practically see thru as the fabric is so thin. I now but at Land’s End and LL Bean as they have sturdier shirts.
Read the comments. Most about the poor quality of Levi’s
