Sia's early albums had a different indie and soul style compared to her current pop and dance style. She gained popularity through hits like "Chandelier" and "Cheap Thrills" and branded her image with a two-colored wig. Sia uses the wig and brands her merchandise to show fans and the world her loyal following. Sia discovered dancer Maddie Ziegler through social media and their collaboration helped boost both of their careers, with Maddie appearing in many of Sia's music videos and becoming a face of Sia's brand.
