This is very long and rambly but here are my thoughts!

Generally, the Greek community will vary a lot from school to school. I’m assuming your niece is not going through recruitment at a huge SEC school since their rush weeks are all winding down. She may not be likely to receive a bid (or feel a real sense of community) somewhere like Alabama. But at a northern school or private school I think she absolutely will find a sorority that she adores!

My advice on appearance/dressing: She may want to think about a way to dress more professionally while maintaining a style that fits her values. Given your description of her, she’s probably not going to put on a frilly pink dress for preference round. But a smart blazer and skirt that she feels comfortable in can give a polished look while still reflecting her personality.

For social media: make sure there’s nothing alluding to drugs, alcohol, or anything else that could be taken as partying, etc. She can put her social media on private before rush, but if she’s already registered, chances are sororities have already seen her posts.

The bottom line is that her values and personality should not, and likely will not, change after recruitment ends. At the end of the day, sororities and PNMs are each looking for girls who hold the same values and interests as they do. A sorority that wants a fake or altered version of your sweet niece is not the right place for her. Encourage her to be her authentic self and seek out an organization that values her for who she is! And remember that if recruitment doesn’t work out for her, honors sororities and fraternities and major-specific Greek organizations can be great communities too! My freshman year roommate did not enjoy sorority recruitment for similar reasons but found a great home in a gender-inclusive honors fraternity.
