Hi, I am interning at technology division of a BB which is essentially back office.

What normally is the usual dress code for back office technology people?
Do back office people wear suits? or dress shirts with dress pants is fine?

I am not in a support role. Also, I saw a joke thread making fun of back office dressing style. I want to look good and don't want to remain a joke so please advice.
