CRUSH PARTY HELP!

[Pretty.in.Pink]

I want to have a crush party with my sorority, but I don't really know how the process works. Everyone gives me the name and address of their crush, I sent out anonymous invites, and then they come...

But I want to think of a cute way for each girl to reveal to her crush who is she is. At one party, guys gave us ties and then we wore them, they came to the party, and took back their tie. How can I do that in the opposite way, with girls?

Thanks for help!
