and the event chair typically picks who is matched up with whom. Typically the "top tiers" plan together, but it really doesn't matter because there are a lot of events where no matter what sorority/frat you go into you will probably have an event with each other chapter at some point (:

I agree with the above, they tend to mix in tiers.
Aphi, Gphi, and Kappa- Lambda and Fiji, Kappas hang out with Delts a lot since Greek week and some girls in each sorority hang out with PhiKaps
AXO and Theta- Beta, sometimes delt and Phikap (but delts party hard and a good amount of these girls don't go out as much)
KD, ADPi- Sigep, Beta, Sigma Pi?

Social chairs plan events and sororities and frats don't necessarily have to mix together if they don't want to. Again, they tend to mix by tiers.

Lambda- Aphi, GPhi
Fiji- Aphi, GPhi
Delt- APhi, GPhi, Kappa
Phi Kap- APhi, GPhi, Kappa
Beta- Kappa, Theta, AXO
Sig Ep- KD, ADPi
Sigma Pi- ???

Aphi, Gphi, Kappa- Lambda, Fiji, Delt, Phikap
Theta/AXO- Beta, SigEp, some Delt
KD/ADPi- SigEp, Beta, ?Sigma Pi?

Girls tend to socialize with more diverse frats, you can find top tier and middle tier sororities at a lot of different frat parties. I would say there's groups from each sorority that like certain frats the most.

Aphi- lambda
Gphi/ kkg- fiji

Axo-beta/ sig ep/ delt
Kd- delt/ sig ep/ beta
Adpi- sig ep
