Clara Cow’s Cosplay Cup


Welcome to the Canadian qualifiers for the Clara Cow Cosplay Cup (C4). C4 is a contest where cosplayers from around the country compete for a free trip to represent Canada at the finals in the Rotterdam, Netherlands. Grand prize winners of the C4 finals walk away with a trip for two to Japan!

What is C4?

C4 is the most relaxed international cosplay event currently organized in Europe, with a main prize of a trip to Japan for the winning team with all taxes, hotel, and Japan Rail Pass covered!

Countries from all over the world compete including China and the USA, with conventions worldwide sending competitors to the Netherlands to have fun on and off the stage. Unlike many international competitions, C4 focuses on performance, so as long as you put on a great performance then you’ll be fine!

Costumes must be at least 70% made by hand and progress books will be expected for the qualifiers. The contest will take place during Otafest and is judged by Cosplayers who have experience in competing at an international level.

This year’s qualifiers will be to select the cosplayers who will represent Canada at Animecon in 2021, so you will have plenty of time to plan and create for the finals!

Costumes + Costume Props

At least 70% of the costumes that are entered must be created by the cosplayers who are entering. Allowances will be made for shoes and other items that are difficult to make from scratch. Wigs will be expected to have been styled by the competitors who are entering.

Any props/weapons that are made for the costume are expected to have been made by the contestant. 3D printing, laser cutting and other modern crafting techniques are allowed. If you think your prop will breach Otafest rules but feel it is important to your performance please let the organizer know as soon as possible so that we can decide whether we can allow it on stage or not.

Progress books containing references, work in progress images, and descriptions of the costume construction are expected from the competitors. Ideally these would be submitted with the rest of your performance information however they will be required on the day of the performance to present to the judges. Progress books can be submitted as a PDF or as a physical book/folder.

Props and wigs that have been commissioned for the the competitors are not allowed. If you have any queries about this please contact the organizer.

Costumes cannot be from a live action movie/TV show, original costumes, or fan art. No alternative designs will be accepted either (e.g. no designs inspired by artists like No Flutter, Hannah Alexander, Zach Fisher, or Gladzy Kei).


The performance aspect of C4 makes up 60% of your final score. The number one piece of advice for any budding performer is to make sure the performance can be understood by anyone who doesn’t know the source material. If you are in doubt, perform for your parents or grandparents. If they understood what the performance was about then you’re good to go!

If you need inspiration there are plenty of performance examples on YouTube. Search for C4, European Cosplay Gathering, or World Cosplay Summit if you want to see examples of what has been done before for inspiration.

The performance doesn’t have fill the entire 150 seconds, it can be a shorter performance if you think it will make for a better story. You don’t want people falling asleep or getting bored. Remember, longer performances doesn’t mean they’re better.


Your audio track is pivotal to keeping your performance on time and to create cues for yourself on stage. The track cannot be longer than 150 seconds.

No live audio is allowed for the contest, this means you’ll have to record your own audio track. There are plenty of websites around for stock sounds like rain, footsteps, explosions, etc. You just need to download them and insert them at the right places.

As for actually building the track, a lot of European cosplayers use Audacity to edit their audio but there are loads of other programs you can use.

All audio must be in mp3 or wav format. No other formats will be accepted. If you need help converting files please let the organizers know.


Video is not be allowed at the C4 qualifiers, however if you qualify to represent Canada in the Netherlands there may be the chance to create a video to go with your performance. More information will be given to you once you qualify.
