As an incoming business major freshman, do I need to have a suit with me? Will I need it for events or will it be better if I just hold off on getting one until sophomore year?
You need a suit once you start interviewing for co-ops - so sophomore year should be fine.
If you have a blazer I’d bring it.
Agree with getting a blazer and even a few button down shirts and ties as a freshman. Pair it with khaki pants and it’s a professional look while attending a career fair or special lectures / guest speakers. Plan on a suit for sophomore year. (Black Friday sales have good deals on suits).
