cold wash or hand wash. hang dry or dry on low if you must. don't buy clothes made of shitty fabrics. stick to natural fabrics. if you're a messy person, buy things that are dark or can be bleached. buy brands that have been around awhile. they're usually still around for a reason (I just know someone is going to say "that's not necessarily true" blah blah blah but it has been for me. lean into a slightly distressed look if you plan to keep things and wear them that long. I happen to think that using tide free and clear has saved my clothes. my mom used all my whole life and that shit didn't clean at...all. lol. I use laundry sanitizer in lieu of fabric softeners or dryer sheets. my clothes last forever.
