(I will add photos later to help with my point across.)
I was taking a trip down memory lane until I remembered something. It was a mix of cottagecore and kidcore/babycore. I'd see it time and time again. I believe on Tumblr it is referred to as Cottagecore agere.
Would this stand as an article on its own? It's varied in its media, but there is a consistent theme as well as having an audience on Tumblr.
