Not too fast, please
Good morning, school! Please listen carefully to these announcements about school uniforms. It is important to respect the school uniform. Please remember, girls mustn't wear trousers; all girls must wear a purple skirt and you must wear white socks. You mustn’t wear black or grey socks. Boys can wear a pullover under their purple blazer. The pullover must be blue: it can’t be grey or purple. That’s the end of this morning’s announcement!
British accent, not too fast, but not too slow either... and original text please :)
