The dress code for NIT Trichy has been removed for girls. The curfew timings of the hostel are more strict for girls than they are for boys.
The amount of freedom that any girl at NIT Trichy gets is very relative. For example, NIT Trichy is way more liberal with girls, when it is compared to VIT where a girl is not even allowed to shake hands with a boy or walk anywhere near to him. But on the other hand, if you compare it with BITS Pilani, then you might think that NIT Trichy is strict for girls. But when it comes to academics, clubs, cultural and technical festivals, there are no restrictions at all.
