Palermo PM or Batignolles Horizontal?

I don't have the Palermo. I own the BH and although I absolutely love how beautifully crafted it is, whenever I use it the straps constantly fall off my shoulders. It might just be me, but I don't have this problem with any of my other shoulder bags. :sad:
 
not a good decision. palermo looks a lot prettier. u can handheld, sling it and shoulder carry it. has a zipper as well. i see no reason why would anyone sell it to get BH. the BH only has one of the multiple function of palermo. so why sell it?
