Pre-judging: what happens and how to prepare

A plain-language guide to pre-judging at cosplay competitions, explaining the process and how first-timers can prepare confidently.

Pre-judging is the part of a cosplay competition where you meet a small panel of judges face to face, usually backstage or in a separate room, before the main stage presentation begins. Judges can look closely at your work, ask questions about your methods, and see details that would never read from the back of an audience. At many competitions it is where most craftsmanship scoring happens, so arriving prepared can matter more than how polished your stage walk looks. When you check in for pre-judging, a handler or volunteer will usually guide you to a queue and then bring you to the judges when it is your turn. Judges may walk around you, look closely at hems and undersides, and ask you to describe how you made specific pieces. Common questions include what materials you used, how you attached parts, whether you dyed or painted fabric yourself, and how you solved a particular construction problem. They are not trying to catch you out; they want to understand the work behind what they are seeing. Your build book is your single most useful preparation tool here. A clear set of progress photos showing raw materials, work in progress, and finished details lets judges give you credit for techniques that are now hidden inside a finished piece. Organise it so you can flip to a relevant page quickly when a judge asks about something specific. You do not need a professionally printed portfolio; a phone gallery, a printed binder, or a simple slideshow all work as long as you can navigate it without fumbling. Practise talking about your build out loud before the event. It is easy to go blank when someone is examining your work up close and asking technical questions, so running through a short explanation of your biggest challenges and how you solved them will help you stay calm. Be honest about what you made yourself versus what you bought or altered, because judges generally respect transparency and will ask follow-up questions if something seems unclear. Each convention's own rules decide the divisions, the judging criteria and what documentation to bring, so read them and shape your answers around what that event says it judges. If your costume involves any heat-formed plastics, resin-cast parts, wired electronics, LED components, or prop weapons, be ready to explain how you made them safely and how they are secured to your body or carried. Some competitions require prop check separately from pre-judging, and staff will tell you where to go. Arrive with enough time before pre-judging opens to complete prop check first if needed, and follow all event-specific safety rules for anything that could be considered a weapon or a hazard to people around you in a crowded backstage area.
