According to my friends studying at Haldia Institute of Technology, yes there is a uniform code. You may feel a bit disappointed after knowing that you will have to wear a uniform to go to college, but the uniform keeps on changing.
Hence, there is a rule of wearing a uniform to the college for every student. But currently, there are three different uniforms provided to freshers, seniors and 2nd & 3rd-year students. And you will have to wear your assigned uniform every day without any excuses.
