From my interview days: At Northwestern, I interviewed with a girl who spent the morning mincing about in a pair of teetering stillettos. That was amusing enough, but the best was when, during the tour, she reached into her massive purse, pulled out a pair of flip-flops, put them on, and dumped the heels in her purse. I was like, wtf?
From my interviewing days: this only sort-of counts, because it wasn't really want the interviewee was wearing, it was her accessory. She brought her mother to the interview. Well, I'm sure the mother didn't accompany her daughter to the actual interview, but this was when everyone was sitting right outside the office of admissions, waiting for us student interviewers to get out of class so we could do our interviews. I really wasn't expecting a parent to be *that* involved. I actually thought the mother was an interviewee; she was older, sure, but she was dressed in a red suit, and I thought, maybe she's just trying to be different. But no, when we did introductions, she was all, "I'm Mom," and smiled at her daughter. I was pretty floored.
And lastly, a tip to all of you who are jet-setting your way into medical school: if your suit is wrinkled and you don't have a steamer on hand, hang it up in the bathroom while you shower. If your suit is wool (or even if it's polyester), the steam will relax the fabric and the wrinkles will fall out.
