Since I am the practical Bag Snob, here is a bag for the girl who just needs to get some stuff done when she goes out. This Stella McCartney messenger is so of the moment in ultra hip faux moss green patent (no animals ever suffer for Stella’s designs). The outer pockets and cell phone holder on the strap makes running errands a breeze. It even has a little loop on the strap to hang things off of. Who wants a black nylon messenger? Leave it to Stella to help us find function and fashion all in one. At Neiman Marcus for $795.
