This is a listing for Jazzie, Barbie's cousin, released between 1988 and 1992. This Jazzie is likely the Highschool Jazzie released in 1988 (the 7th photo is a reference photo of the packaging). She uses the same mold as the Heart Family mom. Jazzie has a unique body, with a smaller bust than Barbie. Her hair is fluffy and in good condition overall. Since she was probably not released in Japan, she is a rather rare doll. You see her less often than the Heart Family. I personally think she looks like Stephanie from Full House. She has a very cute 80s vibe. Shipping is planned via Rakuraku Mercari Delivery Takkyubin Compact.
