Rector Dan Reddiex said the proposed new uniform was in response to feedback from parents, who had raised concerns during the past few years about the braiding on the present uniform blazer.
''The braiding gets incredibly dirty, is impossible to clean and costs $80 to get redone.
''The result is, our most senior boys often have tatty looking blazers that don't do them, or the school, justice.''
Mr Reddiex said the school was consulting parents about changing the present blazer to a navy blue suit with light blue pinstripe.
''As the very fashionably conscious boys have already indicated to me, the trousers would have to change too, to a dark blue, away from the black.
''This [change in school uniform] is a practical decision, brought about by practical requirements.''
It was anticipated the proposed new blazers would cost about $260 each - similar to the price of present blazers.
Mr Reddiex said if the uniform change was approved, it would only be implemented at year 11 in 2015.
''Personally, I just like the look of it,'' Mr Reddiex said.
The seniors who have the present uniform would continue to wear that uniform until the conclusion of their schooling, he said.
Option two was to just remove the braiding from the existing blazers.
Mr Reddiex said it was the least expensive and easiest option to implement.
