Buy a MODEST white dress (no too tight, no too short - if you get a strapless or spaghetti strap dress get a white cardigan as well) and leave the tags on it. Better safe than sorry. The worst thing that happens is you have to return a dress.

Ditto on the don't friend randoms - guys OR girls. Also, don't join or like any sorority-specific groups. If there's a "wayoutwest's school recruitment 2011" group that is OFFICIAL through the school's panhellenic, that one's fine, but better to just observe rather than participate.

If you're thinking of changing up your hair, do it now, so if it sucks it can grow back by rush time. Same if you're getting contacts or lasik or you're going to start wearing fake nails/getting fills. Give yourself time to get used to it.
