Seriously... I've been doing this my entire life. I think I was 14 or 15 when I discovered second hand stores and clothing banks, and gleefully dressed myself in pre-worn clothing. It's been 30+ years and I still do this. You can find name-brand or off-brand clothing, already worn to comfort stage (hello, new (to-me) jeans!). There's also upcycling but I'm too lazy for that... Also, if I do buy things new, I tend to wear it till it wears out (I've had tank tops 5+ yrs which I bought new, and still wearing dresses - galabeya's - I bought in Egype in 2004). Also random thing: Fashion Footprint Calculator kicks a 404 error. But googling: https://www.thredup.com/fashionfootprint is a working site.
