Definition: A matryoshka (plural: matryoshki) is a Russian nesting doll. Nesting dolls are often used as symbols of Russian culture, but matryoshka dolls have their origins in similar dolls made in Japan. Matryoshka dolls are popular souvenirs. It's possible to buy very simple matryoshki in sets of five or seven.
This doll is a new first, since there aren't that many black versions of Skipper. She got a new friend in Nikki, who shared all the fun with Skipper and Corutney. All three girls had the same face and body. The babysitters had the jointed ballerina arms to be able to cradle the babies. Skipper shrunk again in the mid 2000 and there was a Skipper doll included in a big wedding set from Target with Skipper in her old and smiley Teen face - but a smaller body, borrowed from the Olsen Twins.
