Grundie

Grundie is multiple artsy alternative fashion/aesthetic styles mixed together, specifically the mixing of dark and edgy grunge style with colorful and creative indie style. A person identifying as grundie will have a collection of eclectic things that don’t fit into one aesthetic. They may find themselves embracing multiple aesthetics at once, wearing all black with red accessories one day and tie dye with all black accessories the next. They will probably hand make much of their room decor and enjoy customizing or up cycling their clothing. They’ll probably also enjoy a large variety of music genres, from country, to pop, to screamo.

“What would you say that person’s style is? They can’t seem to decide.”

“Oh, they’re probably grundie.”
