It's not just the kids who are wearing uniform at a Welsh school - the teachers have got in on the action too!
Staff at St Andrew's Major Church-In-Wales in the Vale Of Glamorgan are kitted out in school polo shirts teamed with smart skirts and trousers.
Everything they wear is in the school colours of red, white or black.
"It's been a huge success," headteacher Chris Webb told The Western Mail. "The staff love it because they don't have to decide what to wear in the morning."
