Online Sign-ups are open!

Attendees may sign-up at the convention on a first come, first served basis.


The Rules

The following criteria must be met to avoid disqualification:

  • OokiiSoraCon reserves the right to disallow any contestants on the basis of appropriateness of costume; please remember that OokiiSoraCon is a family-friendly convention. If it’s too revealing for the pool, it’s too revealing here. OokiiSoraCon staff has the final say on all entries.
  • All special effects must be pre-approved by OokiiSoraCon staff prior to the day of the contest. Please surprise the audience, not the staff. Any electrical effects must be self-powered. OokiiSoraCon retains the right to disallow any prop for any reason.
  • Any prop or weapon must have passed inspection and be approved by Security and peace bonded appropriately. There will be no exceptions to this rule.
  • Contestants are allowed to bring props within reason. Entrants must leave the stage as clean as it was when they first walked on it. Glitter, confetti, silly string, etc. will not be allowed on stage.
  • Absolutely no flame or pyrotechnical props are permitted due to fire regulations. OokiiSoraCon’s primary concern is public safety.
  • OokiiSoraCon can accept basic lighting requests (e.g. turning the lights down or off).   



Online sign-ups for the Costume Contest will close July 22nd, 2022 @ 11:59pm, or when all slots are filled. There will be at-con sign-ups available for the Presentation category only until July 29th @ 11:59pm, or until all slots are filled.       


As Judges are not always familiar with every character from every show, manga, or game, it is highly encouraged that you provide a photo or drawing of the source of your costume with your entry.

Documentation must be uploaded into an online folder prior to the convention. This includes reference photos and progress shots. Please share a link to your folder in your submission form and make sure they are public so we can see them. These folders will be downloaded Friday the 22nd and any new uploads into the folders after this date will not be accepted. Hard copies will not be accepted due to time restraints of judging slots.

Other Documentation Requirements: All entrants MUST fill out an entry application. There will be no exceptions or last-minute entries allowed.

Costume Contest Divisions*

The Fine Print

The Costume Contest director or representative of OokiiSoraCon both have full authority to eliminate anyone from the competition on the grounds of unsportsmanlike conduct witnessed backstage, violation of the rules, or any other reason deemed sufficient. There is no appeal. Arguing with the director or representative may result in further action taken, such as a lifetime ban on participating in any future OokiiSoraCon Costume Contests.

Contestants are expected to obey all local, provincial, and federal laws and bylaws governing OokiiSoraCon and the venue location. Those who do not comply will be removed from the premises and their badge may be revoked without prior warning. If the nature of the infraction is severe, the proper authorities will be contacted.
