急问：campus visit该怎么穿？

大后天约了Yale的Campus visit。该怎么穿衣服呢？应该不需要biz formal吧？别人上课应该都是biz casual的？大家给点建议好吗？我是女生。谢谢了！

I visited Darden, most women wear business casual, while guys are almost all in suits. You may need to see the school schedule. While if only class visit, casual I think will be ok, coz student wear very casually in class, Darden and Columbia also.
