ELI5: Why do fashion shows show off ridiculous clothes?
gpt
The stuff they show isn't intended to be purchased and worn by consumers.  It just shows what designers will come up with on a clean sheet of paper with nothing holding creativity back.  Further, these radical designs typically show certain design elements that will be toned down and carried over into a consumer line in the near future. 

If you're familiar with cars, think about how automakers show these crazy concept cars for large auto shows.  The manufacturer has no intentions of producing these cars, rather they showcase the direction their car designers will be taking in the next few years on production cars with toned down interpretations of the style elements of the concept car.
