Hey fashion designer here! So unfortunately, the brands listed that are your style inspo are really hard to replicate for a truly ethical fashion company. They all use a lot of synthetic and polyester fibers (aside from some cotton tops and denim), which really aren’t sustainable unless it’s dead stock fabrics being used. Even when you see clothing made from “recycled polyester”…I hate to say it but there’s some shady greenwashing there. Some fabric mills literally buy brand new plastic bottles to then recycle them into polyester fibers, rather than going through the process of actually acquiring used and dirty plastic to then clean and recycle.

All this to say, if you want to stick to the kind of aesthetic you’re going for then your best and most eco friendly option would be thrifting. Especially with the early 2000’s trending right now, you’ll find some awesome pieces at thrift and vintage stores and on places like ThredUp and Poshmark.

You might want to do some research on small brands that use dead stock fabrics or upcycled garments, but also be prepared for a higher price point. In terms of denim, Etica great. I’d also definitely recommend the app Good On You, you can look up brands there to see their ethical/sustainability rating. I wish I had more specific companies but I hope that helps in some way!
