wow alphafrog, you've obviously done this before lol
at my school we have some crazy restrictions on themes...you're only allowed one theme night and its right before pref...we usually do cute letter shirts for the first night and chapter letters for the second, then our theme night (last year we had a sailors ball, this last semester we had asa "one love") and black pin attire for pref...
i remember being really overwhelmed by the sororities that overdid it during recruitment. we tend to stand by the less is more idea, just being ourselves usually sets us apart from the other sororities, and we've been making quota, so it seems to be working lol
although alphafrog's idea is really really cute---just thought id share what we do
