Fun Activities For A Teen Tea Party

My best friend and I are having a joint 18th party and are going with the Alice and Wonderland theme. We like it because its quirky and we're quirky people! We're going to have a pre-(tea)party before the actual party with our closest friends (around 20 people.) What are some fun games (alcohol will be involved) to play at the tea party? I'm looking for suggeborings that will get everyone involved and tie in with our theme.
