Cottagecore is actually the only style where "mismatched" is a feature! The key is to use the wallpaper as a unifying backdrop. Look for a dense botanical pattern or a wildflower mural https://costacover.com/collections/cottagecore-wallpaper. These patterns act like a frame for your thrifted pieces, making them look curated instead of random. It ties the "perfectly imperfect" look together and gives the room a soulful, storied atmosphere.
