what are the sororities with a good reputation?

Hey all,

I've been thinking about rushing next Fall (2014). I am a rather classy girl and I never drink to the point where I am drunk. In fact, I usually last the entire party without picking up a drink, but I still always have fun and have no problem socializing. With the sororities, I am drawn in by the social aspect, but more so by the sisterhood, philanthropy, and all the fun things that come with living in a sorority house. So, are there any sororities out there for me? Which are the sororities with the classier/cleaner reputation? I have the stereotypical sorority girl looks - blonde hair, tan skin. I don't believe in casual hookups with random guys but I definitely love socializing. So, would I be too much of a "goody-two-shoes" to join a sorority? Thoughts and opinions welcome:)
