make sure your wardrobe fits your aesthetic, either by buyin' new clothes or altering things u already own!
I'm not sure about the others, but goblincore is definitely about forest-y colors, darker shades of greens and browns. Thrift stores are always great! It's kind of a bastard grandpa vibe. I'd recommend layering clothes, like collared shirts under sweaters, and pair long socks with like,, Cool Boots.
Patterns are important! imagery of mushrooms, leaves, snails, maybe ur favorite woodland animals, or just like. squiggles.
Overalls also, but probably like brown corduroy rather than blue denim.
Idk what ur into accessory wise but gobs are all about shiny things! if u want, necklaces, belts, rings, buttons, etc.
Steering away from appearance, get out in nature any way you can, collect trinkets (literally anything...coins....bottlecaps....rocks), take walks, watch Over the Garden Wall :), make herb bread, go out in the rain. Sorry if this is incorrect but I think chaotic academia is abt like. Random but brief obsessions with niche things and just learning as much as u can abt em so try doin that!! And talking to other people abt those passions
This is rlly long oml but Pinterest will have a lot of like ~~aesthetic imagery~~ for any one of ur aesthetics that u an use as inspo for outfits or room decorations (goblincore definitely leans on clutter. maximalism ftw) and Spotify will have tons of goblincore/chaoscore/pyschedelic playlists for music 2 get into.
Sorry this was so extensive! hope it was kinda useful! please feel free to ask me any questions
