I don't disagree with your statement here depending on the context of the event.
my assumption, again, is that OP would be the only guy in a suit and tie. you don't want to be that guy, you want to be in same ballpark as everyone else, just looking extremely crisp and put together and perhaps a bit more formal
There is another way to look at this event, and I would want to be just above my peers when defending my department.
As the OP said, he is defending his dept. budget. He has people's jobs, and lives on the line for what he is going to be presenting. He is basically interviewing for his department's position and how company resources are going to allocated. It may very well be that his own future with the company could be affected by how well he handles this event.
Ultimately, the material that he presents is the most important aspect of this meeting. It must be correct, and he must be able to defend his position, his people, and size of the piece of corporate pie that they deserve. In todays market, once you start giving up money, it is very hard to get it back. You do not want to be 2nd string to any other person with whom you are competing.
In buisness be this!
Not this guy!
