18th Birthday Party: Themes?

Question

I need a theme everyone will like, and will be fun to dress up for. Ideas?

Answer 1

My friends and I are BIG fans of themed parties.  Favorites that we've used in the past are:

Jungle (hang fake vines everywhere, have people dress in loincloths, have a kiddie pool filled with jungle juice for drinks)

Cowboys and Indians (everyone came dressed randomly and we had a running beer pong championship against the two teams.  if your parents are going to be there, though, you could always think of another fun game to play)

Derby Party (martinis, big hats, and the kentucky derby on the TV.  what else could you need?  this was a more chill party)

Halloween (when in doubt, let people dress up however they want!  break out your decorations a few months early and celebrate the best holiday of the year!)

Casino Royale (have everyone dress up and set up a good number of poker or blackjack tables)
