I feel like I know this aesthetic all too well. I dub it " Country fairy". It's similar to bohemian but doesn't exactly have that magical element.
Country fairy feels like a mixture of cottagecore, rusticcore, swampcore, and fairycore. Like a princess of the swamp.
The fashion is heavily geared towards women, but men can wear this style too it would just lean more into countrycore.
Flowy dresses (a base of white most often)
a cowboy hat
Fake or real fairy wings
The motifs are
small woodland animals
Rustic browns and reds
White and off -white
