Jem (TV series 1985-1988)

Jerrica Benton is the owner of Starlight Music and the Starlight Foundation, which is a foster home for young girls. But by using her earrings to project a holographic image over herself, she is transformed into her alter ego Jem, the lead singer for the successful music group, Jem and the Holograms. Other members of the group are Jerrica's sensitive little sister Kimber, the strong-willed Aja, and the creative Shana. The group's rivals are The Misfits, made up of the cold-hearted Pizzazz, the tough-acting Roxy, and the humble Stormer. Jem and her friends are always involved in glamorous and exciting adventures around the world, while touching people's hearts with their hit songs. - IMDb
