There's not a lot of bags I would rent, but I'm making an exception for this Karl Lagerfeld Limited-Edition 'Idol' Metal Mesh Tote and Convertible Clutch ($51 per week for members; $57 for nonmembers) that Angela Lindvall carried on the catwalk. How intoxicating would you be walking into a party with it on your arm? It's like having Karl as your date minus the intimidation. There's tons more gorgeousness in the designer boutique so be sure to bag it.
