The Masquerade: Costume Craft at the Worldcon Scale

The largest stage LAcon V will build is not for a band or a keynote. It is for costumes.

The LAcon V Masquerade takes place Saturday, August 29, 2026, at 8:00 p.m. Pacific in the Arena at the Anaheim Convention Center. Individual entrants receive up to 60 seconds and groups up to 90 seconds under full theatrical lighting and sound. Behind that minute sit months of pattern drafting, mold making, wiring, dyeing and fitting - and a judging structure that treats the work as craft first and performance second.

From futuristicostumes to a competition

The tradition starts at the very beginning. At the first Worldcon, held in New York in 1939, roughly 200 attendees turned up in ordinary clothes. Two Los Angeles fans did not. Forrest J Ackerman and Myrtle R. Douglas - known in fandom as Morojo - arrived in what they called “futuristicostumes,” drawn from the film Things to Come and from pulp magazine cover art. Douglas designed and built both outfits.

Ackerman later recalled the reaction on the street: “little children were running in the streets of New York crying, ‘It’s Flash Gordon! It’s Buck Rogers!'” He wore his to the 1939 World’s Fair and delivered a greeting in Esperanto.

The pair wore the costumes again the following year at Chicon, the 1940 Worldcon, which staged the first formal costume event - and, at that second Worldcon, the first judged one. The International Costumers’ Guild has since named Ackerman the Father of Convention Costuming (1994) and Douglas the Mother of Convention Costuming (2016).

Eighty-seven years later the event is a staged, formal, judged production that consumes a substantial share of a Worldcon’s technical budget.

The divisions

The Masquerade’s structure is not a Worldcon invention. It follows guidelines maintained by the International Costumers’ Guild, which is why a costumer’s standing travels with them from convention to convention.

Competitors enter by skill division. Novice exists to encourage people new to costuming and to masquerades; entrants cannot have won competitive awards at events of comparable or larger size. Journeyman is the middle tier, for costumers who have won consistently as novices but are not yet competing with professionals. Open is available to any entrant and is the division in which professional costumers must compete - professionals may not enter Novice or Journeyman. A Young Fan or junior division covers young costumers who design and construct their own work; Worldcons typically set that at 12 and under.

Advancement is by success. Costumers who take more than three major awards in Journeyman are expected to move up. The rule runs one way: an entrant may volunteer for a higher division, but may not drop to a lower one. The point is that novices compete against novices.

Two competitions running at once

The Masquerade awards two distinct things, and the distinction is the heart of the event.

Presentation awards judge what the audience sees - the costume on stage, the lighting, the movement, the brief piece of theatre. These are decided by skill division and by genre.

Workmanship awards judge how the thing was made. Workmanship judging happens off stage, close up, in daylight, with the judges handling seams and linings and asking how a joint was engineered. It is opt-in: an entrant chooses whether to be judged at all, and may ask that only specific components be evaluated. Unaltered commercial items are not eligible for workmanship consideration. Recreations and historical entries are expected to supply source documentation, and workmanship candidates are asked for construction notes.

That combination - a peer-referenced skill ladder, plus a technical inspection independent of stage performance - is what separates a Worldcon Masquerade from a convention cosplay contest. A cosplay contest generally rewards the best version of a recognizable character. The Masquerade rewards original design and recreation on equal footing, evaluates construction on its own terms, and places you against people at your own level of experience. It is closer in spirit to a juried craft exhibition with a curtain and a spotlight, and its serious practitioners also compete at Costume-Con, the dedicated costuming convention the same community built.

Entering at LAcon V

Advance registration is available online, and LAcon V’s current rules list an on-site entry deadline of 4:59 p.m. Thursday, August 27, space permitting. Every entrant, pre-registered or not, must check in at that desk on arrival to confirm details and schedule a rehearsal slot.

Registration asks for contact details, a costume title, genre, skill division, category - original, recreation, historical or assembled - and the names of everyone who made or wears the piece.

The convention is running two stage sessions. Friday offers blocking: basic light, no technical support, a chance for groups to walk the stage and learn its dimensions. Saturday brings full technical rehearsal with crew, where entrants test music and cues.

Worldcon masquerade rules are broadly consistent from year to year. Audio must be pre-recorded. Presentations are held to a PG-13 standard. Open flame, projectiles and anything that sheds onto the stage are prohibited, and weapons require advance approval. Backstage, entrants are assigned den parents, a repair station handles emergencies, and stage crew - traditionally called ninjas - manage props and set changes.

LAcon V’s Masquerade directors can be reached at masquerade@lacon.org. The event also needs volunteers for green room, stage crew and photographic documentation.

Watching it

No ticket is required. Attendance is included with LAcon V membership, and seating is first-come, first-served except for accessibility accommodations, which are handled separately.

Audience photography is permitted without flash. LAcon V is also planning a dedicated fan photography area with a backdrop and proper lighting, which is where the good pictures actually get taken - arena seating is a difficult place to shoot a costume that took nine months to build.

Judging takes time, and Worldcons fill the gap with a half-time show. Costumes are welcome in the audience but not expected; formal wear is optional, and plenty of people turn up in a T-shirt.

Beyond the stage competition, LAcon V will run hall costume awards, with roaming judges recognizing science fiction and fantasy costume worn anywhere in the convention over the five days. That is the older tradition, unbroken since two Angelenos walked into a New York hotel in 1939 dressed for the year 2036.
