Masquerade Full Rules

The Arisia Masquerade is a costume showcase featuring your fellow convention members. It is not a contest where one costume or presentation is being compared to another, but rather an assessment of one’s own skill within their level or the success of pulling off their presentation from the audience point of view.

The Arisia Masquerade will be on Sunday at TBD.

Registering to Participate

The online signup form must be completed by noon Friday of the convention. After that you may register in person at the Masquerade Table. Entrants may change their information up until they leave their rehearsal time slot.

All entrants must check in at Masquerade Table on arrival at Arisia. Masquerade table hours will be: TBD

The Form

Fill out the primary contact information completely, especially the At-Con Phone Number, in case we need to contact you about your rehearsal time slot or have questions about your entry. Enter the title of your presentation next, followed by the genre, skill division, category, costume source, who designed it and who made it, and all the participant names for who will be on the stage for your entry. This information will be read by the Emcee on stage before and after your performance.

The Genre is the category the costume falls under. For example, if it’s a spacesuit it could be science fiction, or something from an Anime show, or from a fantasy story.


For Skills Division Arisia Masquerade uses the guidelines set up by the International Costumer’s Guild:

  • Young Fan Division is for children age 12 and younger in costumes designed and created at home by themselves and their parents. Parents may be part of the presentation on stage as a prop.
  • Novice Division is to encourage beginners in Costuming. Anyone who has not won an award for presentation is considered to be a Novice.
  • Journeyman Division is an interim level to allow further development of costuming skills. If you have won a presentation award at the Novice level you can consider yourself a Journeyman. If you have won three awards as a Journeyman you should consider yourself in the Master level.
  • Master/Craftsman Division is an open class for those who have won at least three awards at Journeyman level. Professionals are considered Craftsman.

For the Re-Creation category you must provide at least one photograph of the original source work. Documentation (movie stills, photographs) supporting your costume will be accepted during rehearsals or in the Masquerade Green Room during Workmanship Judging and will be returned to you following the Masquerade. For Original designs you can also provide documentation to help the Workmanship Judge in evaluating your work.

Indicate if you will be In-Competition or Out-of-Competition. If you have presented and received awards for this costume at other regional or international convention masquerades, then you should consider presenting it out of competition.

Introduction and Audio

The Emcee will introduce all entrants during the Masquerade. Entrants have options for a standard intro, or submit a personalized intro for the Emcee to read. At the Emcee’s discretion they may be willing to take part in the presentation as well.

The only audio heard during the presentation will be the Emcee and pre-recorded audio tracks played by the Tech crew. Any speech on stage will not be heard by the audience. All audio (speech and music) must be pre-recorded and provided at check in. Provide your recordings as an uncompressed WAV file on USB flash drive or CD. Bring multiple copies in case your media become unusable prior to the competition.

Rehearsal, Preparation, and Communication

Possible rehearsal time slots will be emailed with your Masquerade signup confirmation. Saturday time slots are longer. All participants must attend rehearsal or risk being removed from the Masquerade.

Talking to the Technical crew in advance allows them to help you make the best presentation of your costume.

There will be a Head Ninja present at rehearsal to discuss what help you need getting on or off the stage, what prop help you want, etc.

You must clear all special effects with the Masquerade Director and Stage Manager at rehearsal. If your presentation involves removing or leaving any portion of your costume or props on stage this must be covered at rehearsal.
