<p>Definitely pack/buy a sweatshirt. It can get chilly at night, and some events are in the evening. Our D received a coupon for a discount at the bookstore (I don’t remember how much of a discount), buying a sweatshirt or jacket is fun. A pair of jeans for the evening might be a good idea. Bring a backpack for all the paperwork sort of items they collect during the day, and the water bottles, etc. </p>
