Black dress and
comfortable black shoes
White dress (buy now, there may not be any available come initiation time
)
Black pants, khakis, jeans, lettered shirts, a plain solid colored shirt or two... these seem to be staples for recruitment
Nice outfits to wear with your badge
...which brings me to, a badge (duh)
NON-lettered stuff to wear when rush rules forbid you from displaying your affiliation (e.g. during work week, or if you are a rho chi)
Pearls (about 27 of them

A Palm Pilot or other organizer
A camera
An open mind
Patience
The ability to listen
