Me, too!I'm so lusting after a cabas piano! I think it looks like the perfect tote!
i think it's common with most double strap bags, regardless of designer. one of my mj bags is pretty well-worn and the double straps stay up perfectly. the other is the same style but new and the straps don't stay up as well.Me, too!
Unfortunately, I think this is a common occurance with most double-strap LV bags; however, I think over time when the straps start to soften and patina, the shoulder straps will beome more flexible and less likely to slip off.
