Why not theme it "alice in wonderland" - then you can also incorporate in games like "stick the smile on the cheshire cat" etc, and also allows for dress-ups with mad hatters etc?

Or if doing a really girly party, have a look through op-shops for hats, fake pearls, gloves, dresses etc. And do the dress-ups as part of the party? Then do a fashion-parade, take photos and print them out as party favours. You could include cup-cake decorating (to take home with them) and do games like painting a tea-set, or finding a matching set from op-shop finds. I'm thinking cucumber sandwiches, and foil-covered plastic plates to make "silverware" etc.
