I bought a Mono Favorite back in 2016 and the same thing happened to mine. I noticed it while I was at the airport, and I was mortified! I don’t know why they keep making this bag. I don’t think they’ve done anything structurally to fix the defect, so it seems like it’s going to continue to be a known problem for people. I really loved the bag but it stressed me out trying to keep that plate that says LOUIS VUITTON in perfect condition. They took it back and I got a Speedy 25. Thought this was a bag I always wanted, but realized the style in my area is overplayed and I quickly got sick of it. Sold my other DE Speedy 30 for the same reason and used the funds for a stunning YSL envelope bag. If I were you and wanted another crossbody, I would do an Alma BB. I have one in Amarante Vernis and it’s my little treasure box. I adore this bag!
