I happened to be in the admissions waiting room & saw an applicant wearing a zoot suit to an interview a couple of seasons ago. The suit caught my eye, then I looked at the nametag and thought I recognized the name... talked to the guy, sure enough, I knew one of his parents and the parent's sib -- both were alumni and had or were currently on the faculty! (I'd worked closely with one & knew the other by sight).
(cross post on the legacy thread??)
Long story short -- he didn't even get waitlisted. Blown right out of the water post-interview. I'm not saying that it was the suit but it didn't tip the balance in his favor.
