What is the dress code in IMT-Hyderabad hostels for boys and girls? Does it apply when they go out as well? Are there any other rules that apply to them?

When it comes to dress, IMT Hyderabad has little control over what you wear. However, being a prominent B-school, IMT H requires its students to be suitably dressed. On a few occasions, students are obliged to wear respectable business formals. 

Practitioner sessions, leadership talks, classroom presentations, club and committee events, placements, and so on are examples of such occasions. Students are also not permitted to enter the academic block wearing shorts or slippers. Aside from that, you may wear whatever you want and feel comfortable in.
