i'm thinking 70s and 80s prom attire? taffeta, frilly-ness, big hair, etc? funky tuxedos for the fellers. but you could also just throw a necktie on over whatever you're wearing and you'll be good...
<DIV></DIV>or wearyour usualclothes and just greet everybody formally...
<DIV></DIV>
<DIV>"Fantastic to see you again, Mr. Pelletier."</DIV>
<DIV></DIV>
<DIV>The pleasure is mine, Mr. McClubfoot. I dare say, would you care for a swig from thisflask of jagermeister I smuggled in my cummerbund?"</DIV>
<DIV></DIV>
<DIV>"Don't mind if I do. (swigs) Mmmmn, tastes like home. Jolly good, then!"</DIV>
