Well, that's the great thing about freedom of association. XYZ is free to pick their own members based on any standards they choose. If XYZ wants to pick their members based on their looks and their clothes they can. Hey, they have to live with each other. And anyone who does not want to join a group like that does not have to.
What I like about these posters is that they show that sorority women are multi-faceted, and they are not just giving that concept lip service, they are backing it up with evidence to prove it. Which is what I would expect from brainy MIT women!
