I love LV denim! I have the patchwork speedy in blue and it is holding up just fine. I USE my bags.....I don't baby them much. I have a purseket in mine to give it more shape. I also have the neo cabby MM in black. LOVE it as well! I had the denim neo speedy in blue, but sold it to get the patchwork. The neo speedy was too small for me.
I have denim neo speedy in blue and LOVE it. I use it a lot in spring and summer time. It sags but looks good at the same time. If I am carrying heavy stuff, then I place a piece of cardboard at the bottom to prevent the sag. It goes with all my casual oufits!
