HOUMA, La. (AP) — A Terrebonne Parish girl is weighing her options now that school officials have said the 19-year-old student can't attend her senior prom if she shows up in a tuxedo.

Nason Authement, secondary education supervisor, says the policy for each of Terrebonne's four high schools is that boys must wear tuxes or suits and girls must wear dresses or gowns. Authement says the policy is based on long-held tradition.

The ACLU of Louisiana says schools barring girls in tuxes or boys in dresses, or barring same-sex dates, are in violation of the law.

The Courier reports that the civil liberties organization sent out an open letter with that information Friday to high school principals throughout the state.

The prom is Saturday.
