The 1940s Fashiondol mannequin dolls were a learn-to-sew doll and came with a set of patterns.  The dolls were used during World War II to teach girls to  sew.  The doll was made by the Latexture Products Inc. and the patterns by the Simplicity Pattern Company.   The patterns were scaled down versions of the adult patterns available in the store.  In this way girls could learn to sew using a minimum of fabric.  After making the scaled down version of the dress, a girl might then be able to talk her mother into buying the full size pattern to the actual dress.
