While we can thank Greta Gerwig's upcoming Barbie movie for the truly A-plus photos of Margot Robbie and Ryan Gosling rollerblading in matching neon Spandex, we can also thank the film for the rise of a newly coined design moment: Barbiecore. Yes, there's another "core" aesthetic moment happening (also on the list: cottagecore, regencycore, goblincore), The design aesthetic is centered around touches like hot pink, frills, and rhinestones.
