There is no strict dress code as such. Do not be too Informal in the academic surroundings, that's all. This is what the handbook for students states on dress code, "Students should dress in a manner appropriate for an academic environment, be well groomed. Tattooing, body-piercing, hair- styling should be refrained from. " Although it is mentioned in the handbook, No one has ever been told to not wear something. So yes, its pretty chill at RIT.
