As long as the character can be recognized, fans have creative freedom with their costumes. Makeup can help accentuate the look, especially if a character has special features, such as whiskers, elf ears, etc. For example, Naruto in sage mode has orange/red pigmentation around his eyes, MikuCosplay so this is a detail a cosplayer should not miss if they decide to cosplay as Naruto’s Sage mode.
