Valley Girl (1983) on Netflix

Julie Richman is a sweet-natured, if shallow, Valley Girl. After breaking up with her jerk boyfriend Tommy, she is at her friend Suzi's party ("the social event of the season") when two boys from Hollywood crash the scene. One of them, the sensitive and adventurous Randy, is immediately smitten with Julie, and she with him. Julie's friends, however, are not smitten with Randy purely because he is from "Holly-weird" and want Julie to dump Randy and get back together with Tommy. Julie must decide which is more important: her heart and the boy she loves, or the approval of her friends. A side story involves Suzi and her stepmom vying for the attention of Skip the grocery delivery boy.
