There are the art shows, which are where you see the crazy shit that could never be worn as real clothing.
Then you have a layer below that, where the clothes are actually wearable and geared toward rich socialites and shit, but still more or less an art show.
Finally, the layer below that is more of what will hit the high-end stores that season. The mass market fashion.
The top two layers are done so that the designers can sell custom clothing to the rich and famous, and then have their designs adapted to the bottom layer a year or two later. (or weeks/days later for fast fashion)
It depends on the particular fashion show.
