2025 Cosplay Contest Rules
The contest organizers reserve the right in their own discretion to determine whether the contest participants or their costumes comply with the rules stated herein.
- OneAnime is a family-friendly convention. Performances must maintain a PG rating and cannot contain nudity, cursing, or sexually explicit situations. Costumes must abide by OneAnime's coverage rules. (Body paint is not a substitute for clothing.)
- No costumes that are found to be racist (that includes blackface/changing your skin to be that of another real world human race) or derogatory or otherwise promote hate will be allowed. The contest organizers have the final say on the eligibility of all costumes and reserve the right to disqualify and eject competitors found to be in violation of this rule.
- No political or real world religious statements on costumes, props, or signs are to be printed, spoken or yelled from the stage.
- Weapons and props must adhere to OneAnime's security rules regarding peace bonding and visibility.
- Prop weapons may not be brandished at the audience, judges or the emcee. Prop weapons must also be peace bonded.
- No drunkenness or use of controlled substances will be allowed as determined by the security staff.
- No running on stage, skating, or using props that cannot be easily removed (e.g., confetti, glitter, liquids, pyrotechnics). The unauthorized use of those types of props will result in disqualification.
- A contestant may not leave the stage at any point during the skit, either to the sides of the stage or off the front, including stage diving, crowd surfing or trust falling. (Of course, there will be exceptions for emergencies.)
- Competitors should practice good sportsmanship. Sabotage, bullying and/or trash talking will not be tolerated. Competitors will be removed for improper behavior from competition and possibly from the convention.
- Cosplayers who are personally affiliated with the judges are not permitted to compete alongside judges or cosplayers acting as a judge's handler at the event.
