In the 80s, there was a cartoon about a singer named Jem. In real life her name was Jerrica, and she could transform into Jem using her special holographic earrings. I had the dolls, which had streaked pink hair, which you were supposed to hide under a hat to make her Jerrica, the blonde. These pictures are from the artwork on the package, showing what the doll clothes inside looked like.
"Gettin' Down To Business" (named for a Jem song)
"Like A Dream" (also a Jem song title)
