Cynthia- Preview Clip (1947)

From TCM:

Cynthia was Elizabeth Taylor's coming-of-age film, the one in which the intense and determined young girl who had become a star at the age of 12 in National Velvet (1944) became an intensely lovely and just as determined young woman. Based on an unsuccessful Broadway play, Cynthia is the story of a sickly, sheltered teen who rebels against her parents' overprotectiveness, finds a boyfriend, goes to the prom, and gets her first kiss.
