In “Forbidden Fruits,” the fitting room mirror at Free Eden is a confessional “safe space” called Marilyn (as in Monroe) for a clique of mean girls. They run the shop like mall tyrants, each named after a fruit: There’s the feared ringleader, Apple (Lili Reinhart), a gullible egotist named Cherry (Victoria Pedretti) and the self-aware dreamer, Fig (Alexandra Shipp). Good luck joining.
