Dark navy skirt suit (yes...despite my username I am a female, not a transvestite - benny = my poodle). Also, I am really tall for a girl, almost 5'11...so that will probably dead giveaway. What time is your interview? Mine is an afternoon one so I do not have to get there till 11:45.
According to my email about my interview with them, it said if you have an afternoon interview, you have to be there by 10:45. Just FYI in case you misread the information...
