Hello dear

well, generally there is no dress code in the colleges. however, your college may require you to wear formals on certain specified occassion like seminars,moot courst,etc. For example , in my college, students have to wear white shirt and black trousers on college events.if there will be such thing, you will be informed on the first or second day of college so you need not worry about that. feel free to further communicate with us.

hope this would help you.
