Just wondering if these people are waiting to actually buy some Christian Louboutin shoes, or if they are just window shoppers. Personally I can't imagine paying that much for very uncomfortable looking shoes. However if someday I pass by and there's no line I might just have to take a look inside. See how the other half live. The really rich other half with feet that really hurt.
By the way, the French don't say "window shopping," they say "lèche-vitrines," or "window licking." I like that.
