Sorority girls posing in Playboy: It’s a frat boy’s dream come true.

They’re the girls (literally) next door, the ones you drunkenly hook up with after a party and the ones you team up with for philanthropic events… and yet there they are in Playboy. If that doesn’t give you bragging rights, there’s not much that will.

However, sexiness and sisterhood don’t always mix well. For some reason, sororities often seem to have a problem with their members baring it all or even baring just a little bit. Damn those puritanical organizations!

It turns out that many sororities worry about the reputation that will be associated with them when a member strips down. No one worries that much about reputation when the sorority members drink up and head out on a Friday night, but that’s beside the point.

Why can’t girls just express themselves how they choose… with or without clothing and in the privacy of their bedrooms or the public pages of a magazine?

These are the issues that faced girls at the schools below. Check out what happens when sorority meets sex mag:

Michigan State University

Ryan Lovette is the most recent “sister” to feel the wrath of sisterhood thanks to a stint in Playboy. After she posed in “Girls of the Big Ten,” Lovette was kicked out of Zeta Tau Alpha. Her revenge? Another spread in Playboy and plenty of badmouthing.

Clemson University

Zetas really don’t like their members mixing with the magazine. Back in 1998, Playboy came to campus and sororities warned their members against signing up. But Mary Elizabeth Haselden appeared in “Girls of the ACC” anyway and, as such, had to face the Zeta firing squad.

University of North Carolina at Wilmington

Kona Carmack wrote an English paper arguing that Playboy isn’t pornography, but that feeling didn’t extend to her sorority. Even though she didn’t mention the sorority, let alone the school name, in the pictorial, Carmack faced expulstion from Chi Omega so she quit.

Wake Forest

This North Carolina school had a more liberal attitude towards Playboy posing. “Madison” (who preferred not to go by a last name) appeared in the magazine her freshman year, but discussed the issue with her sorority president first. The prez had no problem with it, but warned that nationals might.
