What was said above is sort of true. A lot of it depends on how you present yourself during rush. Like how hard you try. If you spend two hours getting ready and have on a really cute dress/nice outfit with matching shoes and your hair and makeup are flawless then that will definitely stand out that you take care of yourself and are concerned with your appearance. Like was said above some sororities will only take the tall skinny blondes, but more often then not there is at least one or two overweight girls in every sorority. Its all about you and how you present yourself. Besides would you want to be in a sorority that didnt accept you as you?
probably not, at least I wouldnt.
