And it's always possible that the girl she's replacing didn't do her job and she really does have to put a social calendar together for the fall. If that's the case, I think we all can feel your pain. I would get together a committee of chapter friends who can help you work over the summer. And hopefully you can find summer contact information for the fraternity social chairs. And if you're not having to make up time like that, I'd still involve a team.

As far as a formal theme, less is more. I wouldn't get yourself buried under some complicated theme that's expensive and hard to decorate. Look through the party favor catalogues. The pictures will depict current themes.

If I were planning a party for this fall/winter, I'd be planning an End of the World party, probably with a Mayan theme. That will no longer be appropriate by Spring, unless you want to plan a "we survived the end of the world" party, again with a Mayan theme.
