CL obsession rubbing off on other people?

This is tough for people closest me to keep up with. First of all, the cost. My nearest and dearest would not dream of spending the $$$ on shoes. Secondly, the sizing. My poor sister cannot comfortably fit into them. She does have the ability to identify a CL when she sees them in magazines. She's always pointing at pictures of celebs wearing them on the red carpet and she asks, "Do you have that one?"
