"Evening Elegance in Slippers" Dress code: Evening attire with slippers: Wear tuxedos, evening gowns, or casual elegant outfits. Be sure to bring your slippers. The funnier, the better. Also, bring your favorite teacup. I've just moved in and only have 4 cups. From me: I will prepare Chinese Pu-Erh tea. When brewed strongly, this tea can replace alcohol.
