And I just realized in my rambling that I never said what I set out to say in the first place.
Your sorority can be great for this girl. She could blossom into an outstanding member before your eyes, no matter what she looks like. It can be a great experience like it was for me.
However, you always have to consider with each PNM whether they will be good for the chapter, no matter what they look like, what their personality is, etc. Each member has an effect. While a gorgeous yet heinously bitchy member will make your chapter look bad, so can members on the other extreme. That's why you have to really look at each new member as an individual to see how well they'll fit with your organization and its goals.
