Hey, it's a party. Use it as an excuse to dress up if you'd like, we often do.

Be fancy, be glitzy, be casual (but shower, there'll be a lot of people), be retro, be trashy, but most of all, be comfortable. And, going by previous years, wearing something loose around the waist (or that can be loosened) is probably a good idea.

If you are going to be a judge, take a moment and watch the Iron Chef so you can dress in the spirit of the occasion.
