Something to consider before throwing a "Pimps and Ho's" Party is that such a party could be seen as celebrating a system in which women are frequently verbally, physically, and sexually abused in addition to being financially exploited by their pimps. I doubt that anyone sets out to throw a party thinking, "Hmm.. let's see what party we can throw that would celebrate a relationship that is violent towards women" but the truth is that many sex workers do experience much suffering at the hands of pimps. As members of organizations celebrating sisterhood, we really should be cognizant of the issues that affect all women (including those who don't meet the ideals of our organizations) and try to avoid themes that degrade our gender.
I'm realizing that all this makes me sound like a stuffy old woman (I am turning 27 next month) but it is something to think about. I'm sure that there are many other creative theme events that could be held instead. If nothing else, hold a "Sleazy Seventies" party, many of the same outfits could be worn!
Edited to add that I seen "Trailer Trash" socials mentioned in a few threads around here. I'd caution anyone considering throwing such a social could lend some fire to critics of your school's greek system's arguments that greek organizations are snobby. While such a party may be thrown in the spirit of good fun, it could be seen by those who weren't involved (i.e., students who just see the t-shirts around campus) as another example of the greek system making fun of those who come from a lower economic level. Again, I may be being old here, but it just seems like there are plenty of other social themes to choose from that aren't demeaning to others and that won't add to the old stereotypes about Greek life.
