Hey peeps -- especially those of you interviewing at penn
In their email, note that they say "Pack warm clothes: hats, gloves, coats, warm boots will be needed since you'll be walking outside across campus for interviews. Dress is casual--no suits expected or required."
I found that kind of odd and I got in touch with someone in admissions. This person said "As for your dress – lots of people end up in suits anyway... We just like to make it clear that if people are choosing warmth/comfort over business attire it is fine."
Just wanted to let people know (it seems to me at least) that they aren't suggesting jeans and a sweater, rather pointing out that it's silly to wear only a suit and dress shoes if it's 20° with 6 inches of snow on the ground.
