Atwater High School senior girls will wear white graduation gowns this year, the senior class voted last week.
The boys will wear dark blue in accordance with a long-standing tradition, student body president Dion Mays said.
Mays said the tradition changed last year when everyone wore the same color.
In their homeroom classes last Thursday morning, the students voted overwhelmingly to return to the multi-colored gown tradition.
"It's great," Mays said. "We learned how to communicate with the administration better. They are happy and we are happy."
