How The Costume Contest Works

Registering for the Costume Contest

You must register to enter the costume contest. Registration will open when the event opens (8pm for VIP, 8:30 for General Admission), and will conclude at 11:00pm – if you want to be considered for the costume contest, you must register at the contest registration booth before 11:00pm.

Costume Contestants are registered by giving a donation of $5 or more to our charity beneficiary. 100% of the proceeds go to charity. Check out more details regarding our charity partner.

Judging the Costume Contest

We’re thrilled to be partnering with Metropolitan Fashion Week for the judging of the costume contest. A panel of fashion experts from Metropolitan Fashion Week will be onsite to talk with you when you enter the costume contest. They’ll be looking for originality, creativity, attention to detail and overall effort put into your costume.

After registration closes, the judges will review and determine the top 3 entries in each of the 5 categories. We will announce the finalists and publish their names on the big screen. Finalists will have 15 minutes to get to the stage. Finalists must be present to be considered for one of the prize packages.

We will bring the 3 finalists from each category on stage where the winner of that category will be determined by crowd applause. In the event that it’s not possible to determine a clear winner by crowd applause, the judges will determine who wins the category.

Once we have our 5 category winners, the judges will determine, from the 5 category winners, who wins the major prize and title of Best Overall. The judges decision will be final. The Best Overall will win the major prize instead of their category prize. The category prize will revert to the runner up in their category, as determined by the judges.
