I think one of the most success socials that my house did last year was with the fraternity across the street (up to that point we had animosity for each other, for no reason too). We did an exchange dinner, drawing tokens to see which house you would eat dinner at (too many people to do it at one house) and afterward we went to their live out for a party. It was successful because during dinner we talked with the guys, really got to know them. The party was just a normal dance party but it was a lot of fun, a couple other sororities actually crashed it and the guys were not happy about that.

You may not need a theme party to do a social with a sorority. I personally get tired of having to buy stuff to dress up, a normal party is nice and more comfortable depending on the group of people.
