I'll give the OP the benefit of the doubt, she sounds super naive. kcprin, it sounds like "they" don't know what real sorority women are, aside from what "they've" seen on movies and TV. A sorority woman can be anyone. Short, tall, fat, skinny, smart, athletic, nerdy, quiet, blonde, brunette, black, white, green.... it doesn't matter. We are everything. You CAN get yourself recommendations, it just seems like you aren't aware how. Contact the nearest Alumnae Panhellenic group to you.

This is all the info I could find doing a quick Google search for St Louis Alumnae Panhellenic. Do another Google search if there is another group closer to where you live. Ask your high school teachers, church members, etc. You may be surprised at what you can find. Don't say you can't get them without even trying first.
Then create a resume for yourself, highlight all of the awesome things you've done in high school, grades, clubs, work, volunteer, etc. And start doing this now! Don't wait!
