<p>A. Are there any formal events or dances that require a suit or dress shirt and tie that freshman will be attending?</p>
<p>B. Halloween? Do we need to bring some costume to get into the parties ?</p>
<p>I remember my freshman year there were two social dances - semi-formal dress for one of them, casual for the other.</p>
<p>Halloween - you'll see some people walking around campus in costumes and doing odd things. Like one year there was a fight between sponge bob and spiderman on the quad, and another year there were people dressed up like LOTR characters chasing people around with plastic swords. As for parties and other events, a lot of people wear costumes, even if it's a really simple costume that you threw together.</p>
