Hello dear student, 

Greetings ! 

It depends on the college.  Some colleges do have dress code for students while most of the colleges don't have dress code. 

For example,  IIT's any other top institutes do not have dress codes .

So you can confirm about dress code in your own college. 

Thankyou 

Feel free to ask your further queries if any
