Actual Advice Needed for Formal Rush

I was thinking of rushing Zete, and I noticed that many of the brothers and my fellow rushees are Southern. I was wondering whether it is possible to receive a bid without actually being from the South. I feel like I have a pretty good chance as I have managed to cultivate a solid Southern Accent and I recently bought ballasts. I have not been to any drush events, so I just wanted to know if they'll bid me in formal. Also, should I wear the hazers to the formal rush events even though its gonna be night? I have normal straps right now though I bought smathers straps so they might arrive soon.
