People still need clothing obviously (cheap and of good quality preferably).
Also, what do we consider the fashion industry exactly? Most long term clothing trends seem to be dictated by a couple of factors. Consisting of:
- practicality. Jeans are good example of this. It's cheap and practical clothing that lasts a long time.
- cultural "requirement": clothing that is required to fit into social circles. The shirt would be a good example of this, aswell as the tie.
- Enviromental requirements: This one should be obvious ofcourse, No one wears a wool jacket in abu dabi.
Fast fashion and the fashion industry as a whole seems incredibly wasteful to me. Buying new clothing because of yearly trends is way to damaging to the enviroment for what it's worth.
