So anyways I'm a leader of cosplay group that is based in Washington, but this type of group can be formed anywhere and grow. Anyways It's Genki Sushi Cosplay. The object isn't to form a group in a single area, but to create friends who you can all on to join a skit idea or to do a group cosplay with.
