[INSPO] What would you call this style?

Ghiblicore

Mosspunk. Or perhaps Elfcore.

Gnomecore

Moomincore

Peasantry

Clothing

Dark cottage core?

Looks like a variant of Mori Kei

Alice in wonderland on shrooms

Berries and Cream

Floral Cottagecore or Mori Kei

I would say Mori Kei

Dollcore

Boutique.
