I'm new here and needed some help in deciding which LV bag to purchase. This will be my first LV, although I've got quite a collection of Coach, Dooney and Bourke, Cynthia Rowley, and Prada. I'll be having knee surgery soon, so it has to be a shoulder bag. I'm trying to decide between Popincourt Haut and the Cabas Piano. I don't need anything too large, just big enough for the essentials. I'll be using this as a work/everyday bag. What do you girls think.
