School Uniform

The school uniform is required for all students in Years 2 to 11. The school year 2021-22 marks a transition from the old uniform to the new one, and so students may wear either for the duration of the year. From 2022-23, only the new uniform will be accepted.

In June 2020, the visual identity of OIS changed. The uniform with this new visual identity will be ready to buy from our uniform suppliers from July 2021.
