Jane Quimby (Erica Dasher) is a quirky teen with an eclectic chic fashion sense, who lands a job at a hip fashion house when they mistake her for an adult. Torn between her love of fashion and the need to finish high school, Jane conceals her true age to assist the demanding, but talented Gray Chandler Murray (Andie MacDowell), who travels the world in search of the next big style trend. Jane quickly learns that working for a successful executive in the cutthroat world of fashion is not as glamorous as she once thought. But with help from her best friend Billy Nutter (Nicholas Roux), Jane tries to keep up appearances as she toggles between two lives and guard her secret. Even with Billy’s support, will Jane’s ruse be a passing fad, or will she be able to fashion a career in the design business?
A case of mistaken identity has a dateless high school outsider living a double life as a twenty-something career girl in the fashion world.
