This is my first year hosting a party and we are having a costume contest. We included on the invites that there will be prizes for Best Costume, Sexiest & Most Original. I can't figure out the best way to choose the winners. It would be easiest for me to just choose the winners but I am affraid people will think it's biased. But here will be ~25 guests and I think it would get too confusing to just let them all vote on each category. I thought perhaps I could pick 3 to put up for each prize, then people could vote, but not sure how to do the voting. Any ideas or ways you've tried in the past?
