It's actually true that some celebs are being paid to enter the shows. I remember watching Kelly Cutrone's show, and she explained it in one of the epsiodes. She works with PR, so she would know. As far as Olivia goes, she has managed to establish herself as a fashionable "it-girl". That is to say, I would not be suprised if the designers offered her to borrow or get some of their clothes, because they know that young girls will see her bag, shoes or dress and ask where it cames from. It has been shown all lot of times in this forum as well. And from seeing Rachel Zoe's show, I know that celebs can borrow really fancy desinger dresses for big events. So the conclusion is that Olovia probably is well off, but she does not buy all her clothes. She probably gets to borrow them or get them for free.
