Sometimes all you need is lipstick, your iPhone and cash. Then there are times when your purse is so full it rivals Mary Poppins’ bag. From super-small to carry-it-all, you’ll likely find whatever you need in Saks’ handbag department. Boasting designer labels such as Alexander McQueen, Marc Jacobs, Kate Spade and Prada, it proffers glitzy clutches, casual crossbodies, slouchy hobos, trim backpacks and huge beach totes to carry you through any occasion.
