If costume is an original design, then reference images of inspiration or in cases of characters from novels, a printed description from the literary work will be most helpful. Digital devices may be used to present reference photos to the judging panel, but printed materials are preferred.

If you have any special needs, please let the judges’ panel be aware at the pre-judging portion of the contest.

Attire & Costume Rules

Great Basin Geek Con (GBGC) is a family-friendly event in a public location and the attire of attendees must reflect that. Nudity is not permitted, nor are fake, costume, or prosthetic genitalia allowed on display.

Minimum Coverage Guidelines:

Bottoms – Wear sufficient clothing to cover your behind. No cheeks, no genitals.

Tops – Bare backs and exposed midriffs are acceptable. Women must keep their breasts sufficiently covered; no nipple, no side-boob, no under-boob. Men are required to wear at minimum a crop top UNLESS it is part of a character cosplay – if we can find your character with a quick Google search, you can stay topless.

Please ensure that your cosplay is secure. We advise you to do a “wiggle test” at home prior to the convention – bend, twist, and bounce, if anything flashes, fix it. If you feel any part of your cosplay is not secure after getting to the con, please visit our Cosplay Repair booth for assistance. Also, note that these guidelines also apply to see-through clothing and to any clothing that gives the illusion of nudity.

If you have concerns over the suitability of your costume, please contact the GBGC Cosplay Team by emailing

With regards to costumes, please note that:

  • You are responsible for ensuring that all edges of your costumes are rounded off and padded, and no dangerous parts attached (e.g. nails or blades). Examples include full fur suits, armor, wings, tails, and robots. If your cosplay is found to be a hazard to other attendees walking around, you may be asked to remove part of your costume. Handlers are encouraged for costumes that involved pieces that stick out from the body, to ensure that those pieces to not knock into other attendees or vendor/artist tables.
  • Costumes, props, performances, and displays cannot involve or create naked flames, explosions, nor arcs or bursts of exposed electricity.
  • Masks are NOT allowed on the casino floor. They are however permitted within the con and outside of the Sands Regency.

Note also that GBGC may need to take action at the request of the venue or to manage a disturbance caused by attire and costumes contrary to good taste.

Weapons Policy:
GBGC employs a “common sense” policy when it comes to weapons and asks attendees to utilize good judgment when choosing prop weapons.

Actual firearms are not allowed. BB and similar type firearms are permitted as props but must NOT contain any fireable ammunition. Gas canisters or any other vessel containing gas held under pressure are forbidden, regardless of what gas is contained. Common items such as deodorant are unaffected.

If you bring a weapon deemed unsafe by a GBGC Crew Member, you  may be asked to leave the con until it is no longer in your possession. Questionable weapons may be brought to the Cosplay Repair booth for determination. Weapons that do not follow GBGC policy can be left in vehicles – GBGC will not store them for you.

Our mission is to create a fun, safe, welcoming, awesome event where fans of all kinds can come together and celebrate. We want you to not only have the most amazing weekend ever, but to experience it in an environment where you are safe and accepted. As fans ourselves, we understand the importance of creating a safe space for everyone who attends Great Basin Geek Con (GBGC).


If a person engages in harassing behavior, GBGC Crew Members will take prompt action in any form they deem appropriate, including expulsion from GBGC. Our policy applies to EVERYONE at the convention. Exhibitors, Attendees, Speakers, Guests, Professionals, Press, Staff, Volunteers, and Security are all subject to our anti-harassment policy and will be held to the same standards and disciplinary action.


Anyone can report harassment. If someone’s behavior has made you uncomfortable, or if you witness the same happening to someone else, you should immediately contact a member of the GBGC Staff or Security Team, identifiable by red “Crew Member” t-shirts or red wristbands. Harassment is defined by the victim.


If necessary, we will contact local law enforcement, provide escort, offer a safe place, or otherwise assist those experiencing harassment to make sure they feel safe for the rest of GBGC.


Remember: Cosplay is not consent. Keep your hands to yourself unless given permission. If you would like to take a picture with or of another GBGC fan, always ask first and respect that person’s right to say no. If the character you are cosplaying is generally considered rude or abrasive, it is still YOUR responsibility to be respectful to other attendees. Be in character and have fun, but gain consent first!



Please tell a GBGC Crew Member immediately.

We are here to help!
