While there were currently restrictions on hair, make-up, jewellery and tattoos, the law had changed and did not support these.
The traditional woollen jersey would be replaced with a soft material jersey or hoodie.
The blue shirts would be made from a better material, and girls would have the option of shorts, skirts, skirts and trousers.
Juniors would have the option of a polo shirt.
The blazer, which currently has to be worn at school assemblies, would become optional, as would the school tie.
The school would keep stocks of blazers and ties for wearing at formal events.
If the new uniform was introduced, the current one would be also be allowed for a period of time.
