For Syracuse theme, If you could get some vintage white dresses (Vinage Thrift store), serve tea, like a tea party thing. There you could go over the beginning history of AGD. The hair would also have to be vintage looking. If you could find old pictures you could decorate the walls in that along with Blue and Orange decorations cuz those are SU's colors.

Or you could always wear the Blue Sweatshirts with Orange AGD letters and just do a blue and organge theme to represent SU.
