After reading this thread I'm saddened to see that some of the responses mentioned things showing concern with spending $$$ on things that are shown "on the outside" like bags, and with "getting attention" from others. So something like a wallet that sits within your bag, wouldnt matter as much because people wont see it?
I buy designer things because I love them and they make me happy!! Not because people will see them and think I'm cool or be jealous.
