School Uniform

The school uniform is required for all students in Years 2 to 11. The school year 2023-24 marks the end of the transition period from the old uniform to the new one, so students must wear items with the new school logo only.

In June 2020, the visual identity of OIS changed. The uniform with the new visual identity can be bought in the school uniform shops mentioned below. The Parents’ Club regularly hold second hand sales throughout the year where items can be purchased at reduced prices.
