One of my friends studies at Madras Institute of Technology, and this is the dress code system at MIT. There is no uniform for MIT students. But all students have to wear decent clothes to college.
Both boys and girls are not allowed to wear t-shirts and jeans to a college campus. Girls are not allowed to wear skirts too. They have to wear their dupattas on a college campus.
All students of MIT follow the strict unofficial dress code to college. Also, MIT is better than other Chennai colleges in terms of dressing rules. But comfort should also be given priority in college.
Therefore, a proper dressing sense will keep being instructed by other college mates too. So make sure, you always wear decent clothes to the Madras Institute of Technology.
