I completely agree with the advice on how to get into shows. Go directly to the design houses if the press office is being obtuse. Sooner or later, the company figures out they want and need good coverage. In my case, covering Paris fashion, I have learned that the companies of Versace and Stella McCartney are completely consumed with and by celebrity. I have learned to leave them alone-- I no longer consider either a story. Would this change if I found a ticket in my mailbox? I'm not sure. They have been pretty rude many times.
Gianni Versace made my wedding dress many years ago, before he was famous. I'm sure if he were alive, things might be different. But then maybe not!
