My chapter does informal. We are still really small and thus have never reached quota, so we do informal. Our informal is the same set up as formal, meaning we do the same things we do each night during formal but we are the only sorority that does it. We put flyers up all over campus to get girls to come.
The easiest way to stand out is just being yourself. It becomes obivious really quick who is putting on an act and who does not want to be there. If a girl is interested I say go talk to someone you know is greek. All my sisters and myself invite people in our classes or other activities we are involved in. I hope that helps.
