These dolls were sold as K-Mart specials in 1991. Two dolls in Barbie size and a teen doll, all rooted blondes with blue eyes. The two bigger dolls had different hairstyles with one doll dressed in a pink party dress and the other a three colored swimsuit. There were also a variety of fashion sets for them all.
