You might be mistaking modern "fast fashion" with more traditional understandings of "fashion". There is nothing about fashion that requires clothing to be replaced every season. In fact, much of what we now think of as fashion was actually a form of recycling. All of those fancy ribbons, collars, and smocking we associate with Victorian fashion? Those existed to cover up repairs, allow worn out parts to be replaced, and to allow clothing sizes to be adjusted when it was handed down. More generally, fashion is a powerful form of self expression that allows someone to project to the world how one wants to be perceived. Eliminating fashion because it's impractical would be like eliminating art as impractical.
