Square Enix has released full fan kits for every major Final Fantasy XV character. The kits offer up detailed screenshots of the characters and their clothing, so that cosplayers can get the details right. They're currently available on the official Japanese Final Fantasy XV site.
The full list of characters includes Noctis, Ignis, Gladiolus, Prompto, Regis, Cidney, Ardyn, Aranea, and Luna, all of which make sense. There's also characters from the CG film Kingsglaive: Final Fantasy XV, including Nyx, Luna, Libertus, Crowe, and General Glauca. Then there's a kit for food stall vendor and mighty warrior Yamachang.
This isn't the first time that a developer or publisher has offered resources for its cosplay fans. Bioware did the same with Dragon Age Inquisition, offering detailed looks at every cast member. The Dragon Age kits went to the next level, offering exact colors, so cosplayers could get every detail right. In comparison, the Final Fantasy XV cosplay kits are just looks at every character from various angles. Step up your game, Square Enix!
