​
The Main Cosplay Contest is based on craftsmanship. If you enter this, you will be judged on the construction of your costume by our panel of guest judges. This is not the contest to enter if you did not make your costume. Additionally, costumes entered in this contest will be subject to a judging session taking place the morning of the contest; if you cannot attend this judging session, you are encouraged to enter the Hall Cosplay Contest, instead.
Eligibility
Anyone may enter the Main Cosplay event, excluding OS4CA staff. Entrants ages six to thirteen (6-13) must have a parent sign their entry form in addition to signing it themselves as proof of permission to enter the contest. Children under the age of six (6) may enter the contest on their own, but they MUST be accompanied on stage by an adult, in addition to having the contest entry form completed by an adult.
Entries will be capped at 75 -first come, first served. That means: if there are 75 separate Main Cosplay Contest entries before you attempt to register, you will be unable to participate in the Main Cosplay Contest. If this happens, please feel free to enter our Hall Cosplay Contest or Skit Contest; the prizes for those contests are just as awesome.
​
Judging
Main Cosplay will be judged during the judging session held prior to the contest by our guest panel of Cosplay Judges. Judging will take place on Saturday, from 9:00 AM to 12:00 PM and will be located at the Marriott Tulsa Southern Hills Council Oak Ballroom A-C. Judging times will be assigned and emailed after 8pm on Friday of the convention.

Costume Guidelines
-
No costume is NO COSTUME. If the outfit can be mistaken for everyday wear (L from Death Note and Brock from Pokemon, for example), it cannot be entered into the contest alone. However, it can be entered with a group.
-
Costumes must cover at least as much area as a bikini—NO EXCEPTIONS. This is a family friendly event. Please refer to the Dress Code for details.
-
If you did not make your costume, you may not enter the Main Cosplay Contest as an individual entrant. You may, however, enter the Hall Cosplay Contest.
-
A group will be judged solely on those who have crafted their outfits, even if a member dons a store-bought outfit.
-
If you have made heavy alterations to a store-bought garment and wish to enter it into the contest, you must be able to explain how you have altered it and the processes that such an endeavor entailed.
-
Original Characters are welcome to compete and will be judged according to the same guidelines as other entrants. This means: you still need to make your costume.
-
Reference material is HIGHLY ENCOURAGED for fair judgment. We are not always able to look up reference images, so it is best to show up prepared for the contest.
-
Refer to Props Policy for props guidelines.
Limit of Entrants on Stage at One Time
Group walk-ons, where the group simply poses for a picture, may have the entire group on stage, if it is within reasonable size.
​
Time Limit
Walk-ons will be given thirty (30) seconds to one (1) minute to show off all of the hard work they put into their costumes. Please remember not to rush off stage! Being on stage in front of a crowd can be intimidating, but take a deep breath, and show off your wonderful costume by using the full amount of time allotted.
​
Sportsmanship
Poor Sportsmanship is grounds for disqualification from future Tokyo, OK/OS4CA contests, and will render you ineligible for future contests. Be gracious with the placement that you have received. Bullying any contestant or staff is strictly prohibited.
Bullying of any kind is not tolerated. If there is evidence of bullying occurring, the constant/attendee will be disqualified and barred from the competition, and may result in your badge/pass/membership revoked.
Be kind to others who have put hard work, effort and time into their entries.
​
Signature Requirement
Each entrant in the Main Cosplay contest will be required to give a digital signature on their entry form to verify that they have read the rules and will adhere to them on pain of expulsion from the contest. By signing your entry form, you also agree to allow OS4CA to use photos of your costume for promotional purposes via social media.
Winners
Winners for the Main Cosplay event will be announced alongside the winners of the Skit Contest event after the Main Contest concludes.
Winners will be asked to stay after the contest for congratulatory pictures with their prizes.
A list of winners will be uploaded to the Tokyo, OK Facebook page.
***Rules are subject to change at any point prior to Tokyo, OK 2025.***
