Is there any uniform or dress code at NIT Trichy?

One of my friends studied at NIT Trichy. According to him, there is no specific college uniform that has been prescribed for NIT Trichy except for labs. 

• When you visit a lab on the campus, you will have to wear a khaki uniform that is used by the lab.
• The lab faculty will tell you about it during your first visit to the lab. 
• For the dress code, NIT Trichy has mentioned for the students to follow decent and formal dressing manners in the campus in their students’ code of conduct. 
• And in hostel rules and regulations, NIT Trichy has mentioned that the students should not wear a sleeveless dress while coming to the mess area.

The dress code that is usually followed for classes include Formal shirt/pants or collared T-shirts. Collarless T-shirts and tracks are not allowed.
