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 2019 finals in the Rotterdam, Netherlands. Grand prize winners of the C4 finals walk away with a trip for two to Japan!


What is C4?

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 from all over the world sending competitors to the Netherlands to go and 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 on Saturday May 19th and will be 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 2020, so you will have plenty of time to plan and create for the finals!

How can I Enter?

C4 is a competition that is only open to pairs. If you want to enter C4, fill out the registration form below with the costume you wish to enter with and your partner. Once you have registered you will be sent an information pack about how to plan for your performance along with the rules for C4 Canada. The C4 Canadian organizer will help guide you with any queries you may have regarding the contest, planning the performance etc.

Unfortunately solo entries are not allowed for C4. We also do not allow costumes based on live action entertainment, any costumes based on fan art, or original designs, so unfortunately this means no Zack Fisher, or Hannah Alexander designs. Original designs from artists such as Sakizou may be accepted, please check with the organizer before entering.

This competition will not be open to anyone under the age of 18 or Otafest staff members who are directly involved with C4. You must be a Canadian citizen or resident to compete.
