Dolly Style is a Swedish girl group. The group was created by Emma Nors and Palle Hammarlund and features three girls that call themselves Molly, Holly and Polly. The trio claims to originate from a "dollhouse in Dollyville". The group is inspired by the kawaii aesthetic from Japanese subcultures, such as fairy kei, gyaru and lolita. The group has participated in Melodifestivalen three times: in 2015 with "Hello Hi", in 2016 with "Rollercoaster", and most recently in 2019 with "Habibi".
