How about investing in one cool bag this season instead of buying three or four mediocre ones? I'm thinking about taking the plunge with this Silver Marni Balloon Bag ($1,960) that Reese has in brown and black. In the words of Rachel Zoe, "I die." I gave this decadent piece a test run in a store and fell in lust. It's ultra-light and sleek. The shape is '20s fabulous and I adore the utilitarian strap. Does it get any better?
