Important, Personal Question!!

[AMK86]

Hi everyone!
So I'm a transfer student, and I am really interested in pledging a sorority. It has been something I have wanted to do for a really long time, and after our "Meet the Greeks" event it got me even more excited for the prospect of being in one.
My main concern/question is that I am fairly overweight. It is something I am working on changing, but it is just a fact of who I currently am. Aside from that I am very friendly, outgoing, I am the typical girly-girl, I love fashion and clothes, I take very good care of myself, I have good grades/GPA, and I love to smile and meet new people. All of these things are qualities I have been told, and have read from other threads on this site, are important for rush.
My question is, that I hope will be answered honestly, will my size hurt my chances to be part of a sorority?
I'm sure there are exceptions to all rules, and different schools/sororities look for different people, but I guess I'm trying to see that generally would this be detrimental to my making it?
Thank you very much for your help!
