OP, even though you totally bitched out the other people who tried to give you advice, I'll take a crack at it. It doesn't matter whether you're gorgeous or not. What matters is that you feel gorgeous and show that you're confident. You want to show sorority women that you're strong, not insecure. The best advice I can give is to dress in a way that flatters your body. Take the time to find well-fitting clothes. Don't wear baggy clothing, it just makes a person look bigger than they are. Make sure you are well-groomed with clean hair, natural makeup, and nice nails. If you look your best, no one will be thinking about your size, instead, they'll be thinking about how polished you look. Of course, looks aren't everything. You want to make sure your personality shines through and that you're communicating well.
