There is no specific dress code for the students. But you should dress professionally. Wearing jeans, half trousers, and T-shirts during normal college hours is considered inappropriate.
In general, girls can wear Indian clothing like kurta, salwar kameez while the guys are expected to wear formal shirts, cotton pants, and shoes in the college and hospital premises. Apron (lab coat) and ID card are mandatory for hospital or clinical rounds.
Except for this, you can wear all sorts of dresses.
