Cosmo Costume
Float, glow, and grant wishes with this classic cartoon fairy look.
Cosmo from Nickelodeon's The Fairly OddParents is a beloved, dim-witted fairy godfather who is a staple of nostalgic 2000s cartoon cosplay. Often paired with his wife Wanda, Cosmo's look is incredibly easy to recognize and assemble. The costume consists of a simple white dress shirt, black pants, a black tie, tiny fairy wings, a star-tipped wand, and his signature bright green hair and crown.
