So I love cottagecore and royal core but I like a more grunge look. Like a grunge forest fairy.
You can have more than one aesthetic. You can also combine them together.
To be honest asking for that type of aesthetics in here is not a good idea, tumblr or pinterest is a good place than this since there's so many more aesthetics out there than this fan wikia.
Cottagegore comes to mind but that doesn't fit the grunge you are looking for, I put it here for inspo anyway
Edit: I found some Pinterest boards
Currently working on the Combining Aesthetics page, but a bit has been written. Please check there for some tips on combining. There isn't necessarily a name for the aesthetic you're thinking of, so you'll have to work out the details yourself
Grunge and cottagecore!
Here are some pictures of some rooms you might like :)
What do you think?
