I'm glad people liked this thread. People should add in things. Also, its pretty obvious to know you should look your best but I did see some students doing in OCI in things that I might have thought a little too risky. heres what i learned from observation:
girls: stay away from open toed sandle like shoes, make sure your hair is neat, manicures arent' necessary but half chipped off pink paint looks pretty bad, stay away from heavily scented perfumes, bright colored suits are probably not the best idea, stay away from dangling earrings and other gaudy jewlery, and try to stay away from anything that shows too much legs or cleavage.
guys: i really have no clue what is good for them, beyond a nice suit. If guys have any options, please put them here!
