All Natural Loose Clothing in Alt/Goth Style?

Hello everyone!

Recently I have been really trying to live a more natural and "connected to the earth" life style just because I love the way it feels to do so. I really want to get more natural and sustainable clothing as my next step in this identity shift, however I also really love alt and specifically goth aesthetic and mainly dress this way now. I guess I'm just trying to find the loose flowing style of the all natural vibe mixed in with some more goth inspired clothing but I can't find any mashups that I'd want to spend the money on.

Anyone have the same dilemma and/or know where a guy could get something of the sort? Thanks!

EDIT: Thanks so much for all the recommendations, they have all been extremely helpful!!
