updated descriptions

AEPhi - PCs tend to swing between awkward girls, JAPs, crazy partiers, and (more recently) girls who rushed for reputation but didn't make top tier.
AOPi - Long-standing rep as the "nice" chapter, but these days (for better or for worse) more of a mix of girls who don't get bids elsewhere for a wide variety of reason.
APhi - Girls with good (or at least interesting) personalities, but who are in it for reputation. Frats like them, other sororities consider them fake and social climby.
ChiO - There are always some girls who fit the old "eclectic" stereotype, but more and more who want middle tier but don't want the more set reps of AEPhi/DG. What they lack in campus presence they make up for in sisterhood.
DG - Sweethearts and overachievers, and fairly outgoing with a decent number of party girls these days. Seem to be struggling with PR/social media though, so the old rep sticks in a lot of people's minds.
Kappa - Pretty, outgoing girls, with personalities ranging from super-sweet to psychotically mean. Weirdly, has been cross-preffing more with DG and less with Pi Phi every year, but they still consider Pi Phi their rival.
KD - Becoming increasingly well-liked with a reputation for philanthropy and very involved girls, but sisterhood is lacking. It doesn't help that most girls end up there as a second choice.
Pi Phi - PCs range from smart and outgoing to social climby to sloppy, but generally strong personalities. This year's girls are strangely low on the radar.
