I recently attended my university's job fair. While I was there I could help but notice the wide range of clothing that people were wearing. Probably about 40% of people were wearing sports coats or suits, 59% in slacks/dress shirt and the rest...well I did see a few people in sweatpants and a hoodie (gasp!).
While I myself wore a sports coat and dress pants, I was wondering how much of a difference dressing up in say a suit as opposed to just a dress shirt and slacks can make in the little time you get to talk to your next possible employer. (And yes I realize that wearing a hoodie/sweatpants will make a difference.)
Sometimes I feel like wearing a suit to these kind of things can be a little overkill, especially considering that most of the company representatives are wearing some combination of casual dress.
How should I dress at a university job fair?
