I agree with the girls who said that Rush skits where the girls dress up as boys is a turn-off. One of the sororities on my campus did the Grease theme for YEARS, and it was really successful for them. However, when I was going through Rush, I thought some of those girls looked a little too convincing as guys, and the whole skit turned me off to the house. Even though I had really enjoyed the previous parties thrown by that sorority, I cut them for Pref mainly because of the Grease skit. Looking back, that's kind of a shallow reason to cut a house, but all I could think of at the time was that I didn't want to be sisters with girls who could pass as my brothers!
Different strokes for different folks, I guess...
