Now that we have the internet, it may be easier than before to get the scoop on recs, proper dress, etc. If the girls are willing to do the research, a ton of information (and misinformation) is out there. The websites of the nationals of course focus on the wonderful philanthropies that they support while individual chapter websites provide a quick peek into the way the girls look and what they do.
I came from the northeast which was very anti-greek in my area. Nobody's sibs or parents were greek, or if they were, it wasn't discussed. If I had gone to a deep Southern school, I would have been lost and probably cut on Day 1 from everybody because I would not have been able to prepare properly. Then again I would have been lost anyway at a really big school.
The new Alabama DZ is the perfect example of how careful research can help. As related by her dad (with his formidable atty research skills

) they were able to do all the necessary prep work.
