weight & sorority rush

I'm a freshman and I'm excited about rush. I've met some awesome people at the sub dinners. I am really worried about my weight though (because I'm about a size 12). Please let me know if I stand a chance of being considered for a sorority? I know that's sort of a hard question, but I would like appreciate some feedback so I can know what to expect during rush. (My friends say I'm nice, easy to get along with, fun to be around, and am pretty. But, of course, they are my good friends. I love love sports and dance, volunteering, and make good grades, if that helps with my question. ) Thank you!
