You're talking about clothing then, not fashion, fashion is not the antonym of nudism. It's loosely based around clothes but it's not essential to our bodies. Managing temperature, hygiene, safety, comfort, survival, diminishing our bodies' fragility- that's the job of clothing. Nobody needs fashion. It's embellishment and status and attempts to communicate who we are or want to be in a society and more specifically, in a economic system, but it's not indispensable, it's never been and as such, it may or may not have a future in its current form, or as an industry, in even 100 years from now. Industries evolve and fashion as we know it is not even 100 years old, that's nothing in humans' history and as most industries that reach heights fast, the crash always follows and fashion has become too gullible, too sure of its omnipresence and reluctant to listen more than it talks.
That being said, as a career (since this is in the Education section), I think the post below is pure wisdom and accurately mentions all that fashion can still give and become and its exciting and endless possibilities that may or may not remain unexplored... and someone calling it 'disgusting' simultaneously exemplifies the monumental challenge of materializing any of that: it shows the predominant mindset of mediocrity and ignorance while inexplicably behaving as a smug authority that's above curiosity and does not need to know more, slowly polluting and contributing to the imminent obsolescence of fashion as an industry and a world that's brought joy and beauty to plenty of us.
