<p>I should probably shut my mouth (as it were) since my current outfit is almost 100% Banana Republic. But I won't. Theoneo, we only have a few formal parties at Princeton. We actually had our first lawn parties (on The Street) sometime in September. Rihanna came to perform, but that's beside the point. :D For lawn parties, everyone dresses über preppy (mostly as a joke though – I’m serious!). There are kids who don multiple popped collars and the brightest clothes this side of Prospect Avenue! ;) As for the interviewer's remark, you should keep "time frame" in mind. She likely graduated from Princeton AT LEAST a decade ago (if she went on to business school). Things have definitely changed since then (this was a major component of the engaging post-interview discussion I had with my Princeton interviewer last year). I don't know if one can really label one Ivy as the most traditional. "Traditional" is definitely a relative term. What it means to be traditional for Princeton is certainly different from what the same term means at Brown.</p>
