<p>bring lots of different kinds of clothes-- you'll never know what the weather will be! Casual is fine- jeans and a shirt or sweater or sweatshirt is totally acceptable</p>
<p>I'm going, and I think I'll bring a variety of outfits, just in case. Nice slacks and a sweater for the meeting important people stuff, some t-shirts and jeans for the social stuff, pajamas, etc.</p>
<p>since you got in, no need to impress anyone anymore... just sit back and enjoy the ride and hope you get something out of princeton worthwhile since it'll go by very quickly.</p>
<p>Haha, I'm at one right now. People here do dress a little bit better than I thought. Jeans and t-shirts are what most people are wearing, but almost as many are sporting something a little better. Just don't wear real old stuff and you'll be fine though, whatever you choose</p>
