Do you have an awesome costume you’d like to show off at our online convention? You’ve come to the right place!

Submission deadline is July 9th at 11:59pm. Please read all the rules prior to signing up.

The following criteria must be met to avoid disqualification:

  • OokiiSoraCon reserves the right to disallow any contestants on 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. This also includes photographing illegal acts or objects. OokiiSoraCon staff has the final say on all entries.


  • 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.
  • Please consider including multiple photos of your costume. Think of the best angles to show off as much as possible and close up shots that highlight details you are proud of. The max number of photos per entry is 5, not including the reference photo. 
  • Other Documentation Requirements: All entrants MUST fill out an entry application. There will be no exceptions or last-minute entries allowed.
  • Entrants are not required to be online during the Cosplay Contest to participate.
