Costume Policy

With the wide variety of characters and styles seen in Japanese media comes many options available to our cosplayers for outfits to wear to the convention. However, due to Ai-Kon being an all-ages event, we ask that you stress discretion in the costume you choose, how it is constructed, and how you act in it.

While there are no definitive criteria for what will be deemed inappropriate, common sense guidelines will be used in our decisions. Please try to avoid overtly suggestive dress; if possible, modify outfits that may not meet our criteria in a way that will create less issue (ex. shorts instead of a speedo). We also ask that you conduct yourself appropriately in public and not in a manner that may be considered lewd, suggestive, or will otherwise make people uncomfortable.

In the end, what will and will not be considered acceptable at Ai-Kon is up to the discretion of the cosplay committee. If your costume or conduct falls under what we consider to be inappropriate, we will ask you to adjust your outfit and/or behavior accordingly, otherwise you will have to change.

Weapons Policy

For the safety of all convention attendees, please ensure you have read and understood the prop policies of Ai-Kon if you plan on cosplaying.

Failure to comply with the rules may result in your expulsion, without refund, from Ai-Kon.

Misuse of a prop, weapon or any other item even if it falls within Ai-Kon rules may also result in the prop being either taken away from you, or you being asked to leave the convention for misconduct.
