This fall it's all about clutches and crossbody bags. If you're looking for a great small bag that won't break the bank, I suggest the Marc by Marc Jacobs Jane On a Leash Bag ($230 at Net-a-Porter). I adore the mixed metal clasp in front. This functional bag will take you from a shopping trip in the day to an evening out. All you have to do is detach the straps to carry this bag as a chic clutch! Another reason I love it? The interior has card slots so you can ditch your wallet and have all your essentials (cards, lipstick, cell phone) in one compact place.
