What to Wear?

I'm in the process of making a FAQ section for our school Recruitment info page. One question I had asked to me was what types of clothing to bring to school that one might need for recruitment as well as sorority activities. A few of us brainstormed the following, but have we left out something major?

- a white dress (for Initiation and other rituals)

- a black dress (for semi formal events)

- a formal dress (for formals and other dressy events)

- a Halloween costume (for the obvious)

- a nice business style outfit like a pantsuit (for teas, and the like)

- what most people bring for campus living - jeans, t-shirts, shorts, etc etc.

Are we missing out on some major item we should tell girls to pack for school if they plan on being involved in recruitment and sororities? Or do any of our ideas seem way off base? I think this list will really helping incoming students that want to join a NPC sorority. I know I wish I had a guide like this when I came to school so I wouldn't have had to go out and buy a formal gown!
