No, I can objectively say that Paris leads, that the collections shown there set the direction for the apparel industry. I can easily offer you the allegience of American designers to Phoebe Philo, Nicholas Ghesquire, and Ricardo Tisci as an example. And I don't even care for Celine, Balenciaga, or Givenchy but it is clear as day that while you may find some collections in Paris to be boring, Alexander Wang, Altuzurra, Prabal Gurung, and Proenza Schouler do not.
And I can tell you that Givenchy collection, without any big showy tricks, is going to be widley copied and it is directional. My assestment has nothing to do with stage theatrics, I am concerned only with clothes and the message. And when you consider them for what they are, as straightforward as they seem, they were filled with a lot of new and fantastic ideas. Do not misunderstand where I am coming from.
My excitement does not come from my own personal enjoyment as personally I actually like boring clothes (I loved Calvin and The Row), rather, it comes from the expectation of new ideas, new propositions and new directions that will lead the way. Yes, you can't evaulate each fashion week with the same criteria, but even then, even when you recognize New York for what it is, it is only, overhelmingly with few exceptions, derivative.
You can scoff at people who criticize NYFW but the reality is that it is full of much lesser designers and it wasn't always this way. If you consider what American designers had once been capable of you will find no excuses for what they are doing now.
