attractiveness/party girls in sororities

Being pretty definitely helps but if you are pretty but come off as a beotch no one will want you. Looks can only get you so far. I would just look the best you can and remember that personality is key. You shouldnt want to join a group that only wants gorls gor thier looks, anyway

you don't need to fit the "mold" to join a sorority. some sororities may care about looks more than others, but if you worry about whether you will be attractive enough or not to be in a sorority, then you're joining for the wrong reasons.
and honestly... you don't want to be a part of a sorority that cares a lot about how their sisters look and how hot the frat guys think they look... trust me.

The chapters - even the ones with lots of gorgeous girls - don't care about looks as much as you might think. Like others said, you can be drop dead gorgeous but come across as a total jerk and they'll cut you. They're all looking for sisters, not dates lol

Similarly, you might not be a beauty queen but you may be funny, awesome, outgoing or just click really well the sisters. That's all that matters in the end.
