Why did clothes ever become NOT boring in the first place? Clothes are above all something that warms/protects/hides us from the world. Aesthetic contemplations are really just an afterthought. Also, "fashion" is one of the stupidest things ever, like oh hey, you should now replace your perfectly good clothes every season because someone says so??
For my case, for most of my life I hated thinking about clothes, hated anything other than big hoodies/jeans/jackets, saw it as purely utilitarian. Eventually after some soul searching and realizations/some new medication, I have discovered that I quite like using my clothing to express myself, my mood, what I'm doing, and so on.
Fast fashion is very dumb though in my opinion. No reason to be wasteful and throw things away, but there's a middle space that can be very rewarding to explore - the first time I put on a skirt was quite literally life changing.
